yes, but I don't know if he would be willing to delete the account, i'm not sure how much in the database he would have to change or how hard it would be ...
I once asked Simon to rename one of my saves, and he said no because he didn't want to have requests like this all the time where he has to go into the database.
@GreenFireDragon(View Post) but then there are a bunch of leftover references in other places like forums posts, saves, comments, pm's, ban histories, tag histories, and also there will be an empty hole in the user id list. Every id is taken incrementally, there are no holes.
I'm not actually sure how the database works, but I doubt it would be that simple. Renaming is simple since the user name is probably just stored in one location. ID is (I would hope) the one used everywhere in the database to identify the user.
