I think there should be a 2nd house from the beginning of the series with replacements for people who want to walk. The 2nd house should be part of the live feed but not get any tasks or do nominations or anything like that, just live there until called upon to replace a walker from the main house. Then, whenever anyone from the main house decides they want to leave, BB can kick them straight out the first time they come to the Diary Room and say they want out, no messing about, no sleeping on it, nothing - they come to the Diary Room and say "I want to leave" and BB can go "Fine, exit via the door to the left" and within an hour a new housemate can be in the main house. There could even be voting for which 2nd house resident should replace the walker, so viewers get a bit of a say in it. It would also mean you don't get new housemates who've watched the show and know more than the others about what's been going on.
