I like some of those ideas

I like the idea of it either being Sharon's ex husband or Biff's dad being the next one. I also like the idea of Mikey being in high school and Sally trying to go on the dating scene. I had thought that the next person could swap with 1 of these 3 options; 1. A fashion model 2. A rich stuck up wife (who could possibly end up as Zoe's wife. I had pictured her becoming a rich businessman) 3. A prostitute or possibly the school slut Just a few ideas. Or if we do another female swap then she could become a stereotypical man type character like a builder or something
