This is my idea for Big Brother season 13. Eight house-guests should enter the house premature (like in season 4) all eight would be new contestants. Then while they are sitting around with their champagne in walks in 5 previous house-guests, all who have won America's Favorite Player. The 5 would be:
1) Brittany Haynes BB12
2) Jeff Schroeder BB11
3) Keesha Smith BB10
4) James Zinkand BB9
5) Janelle Pierzina BB6/7
I think also Pandora's Box should be renamed Fan's Box with America's Vote being involved (America's Vote with the food is dumb) so either another past house-guest would be unleashed (like Jesse was for season 12 with Brittany and Rachel with Brendon) or past annoyances like clowns from season 11 or other annoyances.
