Oyy, that should be useful.
I also hope that in this case, there isn't a too big difference between modding 3D characters in Brawl and modding 3D characters in Project M, because Mewtwo in that mod is in the big need of an update, and I already have plans for it (touching up some minor animations, new Final Smash, someone already made a SM4SH soundpack for PM Mewtwo so that's out of my list).
