This issue is pretty much black-and-white, from a legal perspective.

In your case, the simple existence of this thread serves as more than ample evidence that whatever product of your work will legally be considered a derivative work. You have obviously been taking bits and pieces of the original and changing and/or remaking them. Reproduction of original copyrighted material in whole or in part is illegal unless explicitly authorized by the copyright holder (which is vBulletin.org in this case).

I'm not sure about any PM messages you've exchanged, but I don't see any explicit authorization from the copyright holder in this thread.
