Considering how little the roleplay aspects of the character creation are, I don’t think it would be too big of a deal to allow us to change the personality/voice lines our character uses when we go to the Barber-Chirurgeon.
Also, if I want to change from a Germanic bald doktor to a suave African sage, I’d like to be able to stop having the high pitch screeching voice that, while entertaining, is very specific to a certain character archetype.
