Plot Bunny running rampant.

[supreme_being81]

I have this plot bunny which seems to have taken root in my head. It wont leave, but I just don't see how I'll do it without major headaches and work. And yet...Has anyone seen Dollhouse? The series with Eliza Dusku in, about a company who hires out actives (people with their personalities wiped, and are thus able to be imprinted with other personalities and skills) to very rich clients. Want a girlfriend who truy loves you for three days? Got it. Need an assassin? Got it. But then the actives start remembering their previous imprints, gaining their personalities. I think it could work REALLY well in the Harry Potter world. But...it's a bit "Eek!"

Anyone have thoughts on which HP characters could sub for the Dollhouse characters? Should I go with the same kind of plot as Dollhouse, or a totally new one?

Help!
