This idea has already been requested multiple times though It probably won't happen because of the family game-meta in place. People (mostly for kids) will remember a friend if their face and name always looks the same.
Kingsisle has hairstyles so they've definitely been paying attention to requests like these but I doubt this will happen.
I wouldn't want to give up on this idea at all but it's been stated more then enough times already.
We should all really get some sort of voting poll going or something. I have a hunch that if we got support from some of the more popular wizards out there like the Friendly Necromancer or Blaze Lifehammer the idea could take off. KI has a good relationship with players who happily and actively support their efforts.
Lets show them we care and who knows! Crossing fingers.
