If anything, I clearly see that the Gentiles who believed there are those of God's elect that did so some years after Pentecost...
During the time of what we know as "the New Testament".
Yes, but Dave, before Pentecost they were already declared righteous, and justified, just like Abraham. If their OT faith was a genuine saving faith, then they will hear and believe the Gospel per the Fathers promise to the Son that He would not lose one of them. The OT already declared righteous believers who heard the Gospel and trusted in Jesus before the Cross were given the right to become Sons of God (John 1:11-12). That promise was fulfilled at Pentecost with the indwelling. Other true OT believers, after Pentecost, already declared righteous by OT faith, still needed to hear the Gospel so that they would believe and receive the Holy Spirit as promised, thus, the birth of the Church and the transition (all true OT believers hear and believe the Gospel). The OT dead, like Abraham, who were also already declared righteous by faith, and died having not received the promises (Hebrews 11:13), also heard the Gospel (1 Peter 3:19), and received them. Now they too could be with the Father.

Before Paradise is in Hades.
Luke 23:43 And Jesus said to him, "Assuredly, I say to you,
today you will be with Me in Paradise."
Jesus Ascends (With OT true believers already physically dead, like Abraham, etc.)
Then Eph 4:8-10 Therefore He says: "When He ascended on high, He led captivity captive, And gave gifts to men."(Now this, "He ascended"--what does it mean
but that He also first descended into the lower parts of the earth? He who descended is also the One who ascended far above all the heavens, that He might fill all things.)
When Jesus ascends, He takes Paradise with Him. Paradise in the third heaven.
2 Corinthians 12:2-4 I know a man in Christ who fourteen years ago--whether in the body I do not know, or whether out of the body I do not know, God knows--
such a one was caught up to the third heaven. And I know such a man--whether in the body or out of the body I do not know, God knows-- how
he was caught up into Paradise and heard inexpressible words, which it is not lawful for a man to utter.

And all that the Father gave the Son, except Judas, were believers of the Gospel and saved. The transition is over. A failure to recognize that unique and unrepeatable point in time will have you using Scripture from both before and after the DRA as if they are the same, but they are not. The context makes them different. What are the things? The death resurrection and ascension. The giving of the Holy Spirit (indwelling). The birth of the Church. Placing [OT] members into that Church, Jesus, The Gospel being revealed as a means for entering that Church, Jesus, and receiving the promises. The realization of the receiving the actual righteousness of God that was declared to all OT believers by promise. Atonement realized. The promises are fulfilled at that transition. These are not things that always were.
But, I do agree that they were Gentile believers ....
Who had no knowledge of what the Lord Jesus had done for them on the cross up until that time.
Exactly. Yet they needed to hear.
John 6:37-40 All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out. For I have come down from heaven, not to do My own will, but the will of Him who sent Me. This is the will of the Father who sent Me, that of all He has given Me I should lose nothing, but should raise it up at the last day. And this is the will of Him who sent Me, that everyone who sees the Son and believes in Him may have everlasting life; and I will raise him up at the last day."
These are the OT true believers already declared righteous by faith. It doesn't matter if they hear and believe the Gospel before of after Pentecost, just as long as they believe the Gospel before they die, which everyone of them will. The before and after only dictates when they will receive the promises of the Father, mainly, the Holy Spirit indwelling, which makes them one with Jesus, officially, literally justifying them and making them born again, so that they can now go to be with the Father (John 3:13-15).
John 10:23-30 And Jesus walked in the temple, in Solomon's porch. Then
the Jews surrounded Him and said to Him, "How long do You keep us in doubt? If You are the Christ, tell us plainly." Jesus answered them, "I told you, and you do not believe. The works that I do in My Father's name, they bear witness of Me. But you do not believe, because you are not of My sheep, as I said to you. My sheep hear My voice, and I know them, and they follow Me. And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father's hand. I and My Father are one."
The Gentiles, the true OT declared righteous by faith believers God is bringing them the Gospel, even after Pentecost. The transition is over when all the genuine OT believers hear and believe the Gospel.
You can see this all throughout Acts. See Acts 10.
