Doubtful.
As much of a pain as it would be to do, I think your best bet is just to make a new account, copy all the information you can over to it (user profile, copy and paste pages of your storygames, etc) and then just tell everyone that the new account is you.
If it's done properly, the only thing you'll notice that is different is your saved PMs and previous posts won't exist. That and your post count and points (personally I don't think they matter too much though).
