Would it not be better to understand the 7 Seals, Trumpets, and Bowls as concurrant rather than chronological.
Not really, no, because as I said it is the differences, just as the OP points out in regards to the differences which disqualify the events as the same in the two passages.
And how much different do they need to be in order to distinguish them as separate events?
For example:
Revelation 8:7-9
King James Version (KJV)
8 And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;
9 And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.
Revelation 16
King James Version (KJV)
3 And the second angel poured out his vial upon the sea; and it became as the blood of a dead man: and every living soul died in the sea.
While similar in nature, there is a discrepancy in the total of those who die, demanding a separate event, excluding the possibility of concurrence.
It is the differences that tell us we are not looking at concurrence, but that each judgment proceeds after the one before it.
They seem to to be a Recapulation with an increased intensity.
Many take this view. I cannot.
Just as a suggestion, try giving Revelation a look with a sequential order in view, and see if it does not make more sense than it does when we try to force a more symbolic interpretation of it. You will be able to create a timeline which makes it easier to understand.
For example, Rev. 11: 15-ff seem to be referring to the End
Rev. 11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
16And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
17Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
18And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
19And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
Many believe it does, Those who are Post-Tribulation believers also take this view, however, this requires we ignore the order given by John. Christ's Return is clearly depicted in Revelation 19, and this depiction stands in harmonious consistency with Old Testament Prophecy.
What is in view here, if you stop to think about it, is the fact that the rule of Satan and Antichrist, meaning the leeway they have been given up to this point...ends. From this point out they become powerless against the efforts of God and become players on the stage.
Just as Satan told Christ...
Matthew 4:8-9
King James Version (KJV)
8 Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them;
9 And saith unto him, All these things will I give thee, if thou wilt fall down and worship me.
...and Paul wrote...
2 Corinthians 4:4
King James Version (KJV)
4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
...we understand Satan has been given a certain amount of authority in this world. That does not negate the rule and reign of God, nor that He is the Only God, but we have to take this into account.
At the sounding of the Seventh Trumpet Judgment we see God step into physical world and His authority becomes the only authority. We do not see Christ return at this time, and in fact we see that still pending are the Seven Vial judgments, which can be distinguished from the previous two sets of judgments. Unless we discount the fact that these take place we are forced to leave Scripture intact and keep the order of events as they have been given to us.
When Christ does Return, those enemies who suffer through the Seven Vial Judgments are destroyed, and following is that depicted in Matthew 25, which is the Sheep and Goat Judgment, which is not a Rapture event, but in fact is a physical judgment upon the unbelieving, who are destroyed because nothing that offends shall enter into that Kingdom He establishes upon His return.
We see this made clear here:
Luke 17:34-37
King James Version (KJV)
34 I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
35 Two women shall be grinding together; the one shall be taken, and the other left.
36 Two men shall be in the field; the one shall be taken, and the other left.
37 And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
Some mistake this for a Rapture event, but the opposite is true. Those "taken" (and look at the Greek, lol, very interesting) are, as taught by Christ, physically destroyed, there flesh left as carrion, as taught also in Ezekiel 39.
This corresponds to another Second Coming teaching:
Matthew 24:27-28
King James Version (KJV)
27 For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.
28 For wheresoever the carcase is, there will the eagles be gathered together.
So you see, when we keep everything in it's proper order, we see that the Return of Christ does not result in a Rapture event, but instead results in believers who are physically alive being "left" to enter into the Kingdom, and unbelievers being "taken" in judgment. And when it comes to resurrection at this time the only resurrection spoken of are those who die in the Tribulation. The dead in Christ are not raised at this time.
He shall gather all for this purpose, setting the believers to one side, and unbelievers to the other. Believers remain alive (not glorified, as in the Rapture described by Paul), and unbelievers die physically (not eternally, as they do in the Great White Throne Judgment which takes place after the Millennial Kingdom). This makes it an impossibility to place the Rapture of the Church during these events. And if we maintain the Word of God we see that after this event comes the Millennial Kingdom, which also coincides with not just the testimony of Biblical Prophecy, but the very Promise of God.
No Promise of God goes unfulfilled my friend, and while some of our brethren see all promises fulfilled, they are hard pressed to keep Scripture intact and have those fulfillments not come up short. For example, seeing the First Century as fulfilling Revelation might seem plausible, and I would go so far to say that it would be in keeping with the multiple applications we see concerning Bible Prophecy, but...in no way can it be said to be fulfilled to the jot and tittle.
That still remains.
God bless.
