No, No, No, No, No, and No.
You can try, but God is not obligated to accept all "worship" offered to Him. What is the difference between true worship and vain worship?
Vain worship is done according to the doctrines of men. True worship is according to truth. God's word is truth.
Why did God not accept Cain's offering? It was not in faith. Yes, it was in sincerity, no doubt. Cain even became angry that God did not accept his offering. Abel offered his in faith (Heb 11:4), (faith comes from hearing God's word, so God told them what to offer - Rom 10:17) and though he is dead, he is still speaking.
There are a lot of Cains out there expecting God to accept what ever they want to offer, regardless of what God has said that He wants. The only way we can know what God wants in worship is He tells us in His word. That is why we MUST worship in truth (Jn 4:24).
If you follow your line of questioning to it's logical conclusion, then anything not expressly forbidden can be offered to God in worship and He will accept it.
Nadab and Abihu stand as strong examples that we can learn from. They offered strange fire that "God had commanded them not". Fire is fire, right? Not in God's eyes (Lev 10:1-3).
Can I worship God in eating yeast rolls with honey and butter? If I really like it and decide to add it to the unleavened bread on the Lord's table, because I like it and God didn't say not to, then what's wrong with that. I then force others to accept it or "worship" somewhere else. I convice others to accept this practice until it is the norm and those who don't are looked upon as strange. Churches are split, groups divided, and others are ridiculed, just because some people force what they like on others, without regard to what God has said. Yes, you still have the unleavened bread in the Lord's supper that is eaten with the yeast roll and it tastes so much better this way. God didn't say not to, did He. Surely God will accept this. I can worship Him in the shower or while eating a yeast roll with the unleavened bread during the Lord's supper, right?
No thank you. I'll stick with what God's word says and what they did in the early church. I'll stick with my unleavened bread and "unleavened" singing, just as God commanded.
