they could keep it, no harm done in keeping. it would actually be fun to play imposter battles that way. Zelda's just being Zelda. personally i always thought she had an elegance about her that far excedded peach and daisy. Rosalina might be able to match her. in fact its kinda like this:
Zelda: elegant, graceful, gothic
Peach: goofy, cute, klutzy, classic princess
Daisy: Tomboy, rough, rub in victories, sports queen
Zamus: sex appeal, ***** w/ the whip, fetish, Standard female fighter in other fighting games, think Ivy from SC.
Krystal: furry, sex appeal, overated
just throwing some things out there.
