I don't know anything about the mechanical aspects of this game that don't involve playing fighters, and even then I'm on the low end. This might be OP for wizards I have no idea because I've never played one but its my favorite idea that I've ever had and I really like all my stupid ideas.
Special credit goes to Waffles for remembering head model sizes can be increased independently of bodies.
