Same Account Different Username?

Hey, I know that we will be able to transfer our current username/account from DF to DF2. However, I was wondering if we can still transfer our current accounts to DF2 but change our usernames for the new game. I know since I created my account when I was high school I gave it a really dumb username. So I guess what I am saying is, can we still transfer our accounts over with the option of switching our usernames to something else?
