Hey there! Thanks for your patience.
So we've decided that frankensteining is not allowed, since you aren't actually creating anything, you're just modifying. However, you are modifying something other than the bae RMMZ assets, so that is outside of the scope.
However, tracing, if we understand it, is OK since you are creating something based on another thing, which is still creation. Obviously, if you are creating an exact replica, then we'd have no way of knowing that it's traced and not copied, which would be problematic. However, if you take a sprite sheet and trace over it to create your own, that's fine. Like taking a sprite of Sora from the GBA Kingdom Hearts and tracing over it to pixel-make Roxas. Hopefully, that makes sense.
Please let us know if you have any other questions.
