I know this has been said before, but I think it bears repeating. Instead of spending all your time and energy re-designing preexisting characters that you don't like, just make your own damn superhero characters.
Honestly, I wouldn't mind a short-haired, more muscular female superhero, but let the design and character stand on its own merits. Don't just slap your ideas on another person's hard-work.
*Editing this because I just realized I redesigned Andrew Dobson's stupid pirate characters in the Andrew Dobson thread. I'm a dirty hypocrite, but my point still stands!
