I don't think of "clone" movesets as too big a "problem" as long as they have different properties and the characters play in different styles.
It's lazy and a waste of a character spot imo. Ganon being a clone of Falcon makes no sense at all when he could have his own set. Falco is essentially the same as Fox and could be replaced with Krystal. Ness/Lucas learn different special moves I think so there's no reason for them to be the same either. TLink could have moves based solely on WW and be different from normal Link. etcetc
