Do you think kit would work? I remember seeing it America's Player in BBUSA10 when Dan did it (who went on to win). Basically, how we could do it here, around Week 6 (mid series) we can vote on the website who we want to become "Britains Player"... it can only be done once in the series so its more effective.
Basically, whoever wins and gets the most votes, will be controlled by US, not Big Brother for the week. On forums, website etc... people will post what tasks/missions they want this particular housemate to do, with 1 each day, some more subtle than others, and mess around with the housemates heads... from intense tasks to more silly ones that make them look stupid and make HMs think "WTF is wrong with them?"
Would it work?
