Does that seem narrow minded? Suppose you were running a serious game of D&D and one of your players wanted to re-skin their PC into a Smurf. In that case, the groups fun takes precedence over one player's poetic license.
I'd assert that this is a problem with the specific reskin chosen, not the reskinning concept in general. A disruptive player will be disruptive no matter what house rules are or aren't in place.
