Well, if I wanted to add it, I'd have added bones with the bone adder.
And I just might get back to hacking now. I'm going to keep up the work for a Version 2 release of Tabuu. It will include more animations (new ones and revamped old ones), new attacks, new sounds, some new graphics and etc.

good to hear here is some missing animations list i noticed to help you if you dont know already xD
missing/ need to be fixed animations:
needs landing damaged animations
edje equilibrium animation(dont know the name :S)
needs edje jump animation
up tilt
up smash
fixing grab items animations so the chain isnt out
up/down/back trow animations
side smash isnt working maybe animation problem??
also for up smash and up tilt you should check ZSS and how she uses her whip xD
