Have spoken with the developer support team and they didn't really understand... Suppose I am approaching this from both a consumer/developer viewpoint.
They think I need 2 accounts, one as consumer, one as developer. Fair enough.
Basically I was wanting to try my hand at developing on iOS, but would like to sort out a new e-mail address now and don't want that to change later on. The e-mail address I want to use, is an existing alias. I hate multiple accounts for anything so that's why I wanted to consolidate. Plus, based on problems I have had with MobileMe, and my local Apple Store, they are willing to refund my family pack on a pro-rata basis. This should then cover the cost of the dev program.
