Why are you trying to find out what the extreme end of what could be allowed is? Instead, why don’t you focus on making decent music that is definitely allowed?
I don’t see the point in this at all.
Read the following link which tells you what Envato’s policy is about this.

To be on the safe side, I would just refrain from using melodic audio loops altogether.
I’m not posting personal stuff. I’m stating that Audio Jungle doesn’t need any new artists who are going to upload tracks made up of audio loops like yours is.
It would be impossible to turn any part of your track into an ident for Audio Jungle because none of it is original material.
There’s a pretty straight forward answer to all this. Don’t upload tracks like this. Write good music with your own melodies and harmonies and upload those instead. And if you can’t do that, take your music somewhere where they allow you to sell tracks like this. (I’m not sure there are many legitimate places that would though.)
