Think about how it would most likely play out, and you come to the conclusion that it would most likely be Rupert shuffled from tribe to tribe every other week. He is the one each tribe would most likely "loot" from the other tribe, and he'd become a human ping-pong ball. The thought of this sort of twist only effecting one person seems boring, and not worth attempting.
Plus I really don't think it's fair to anyone from a strategic point of view. This week Christa stood a good chance of getting voted out. If the votes were closer she might have needed Rupert's vote to stay, and she wouldn't have had it. The game of survivor depends alot on human interaction and alliance building. To lose or get booted because one or more members in your alliance decided it was time to turn on you and boot you is one thing...that's part of the game. To spend time strategizing, building alliances and protecting yourself just to have someone come take you out of the tribe, and mess it up doesn't seem fair...even if it is only for a few days. We have already seen how the unintentional and unpredictable absence of one your alliance members can nearly cost a person a fair chance at staying alive in the competition.
Others may see it much differently than myself, but this is just my opinion.
