I know this mod has already been done (it can be found here), but I don't feel like the modder got the face quite right. It looks exactly like Super Buu's original face. Buutenks' face should have a much more pronounced nose, and I think his mouth should be a bit more human-like. I'm wondering if anyone could create something similar to this:

The face is really the only part I'm concerned about. If someone could make a face that lines up with the rest of the existing mod, that would be cool.
