Havent read too much on this topic, but its got me wondering, is it possible, to use a model for a new race? heres an 
example:
Use the Old Froglok models,  Start them off in Guk and work from there. exc. I know some of the Models dont have the dual weild look, and some animations, but i just wanted to know if its possible, and the difficulty level.
Thanks, much appreciated
