Here's the part that I think would break the rules, or at least be unfair and/or unethical in a game show situation:a. The contestants and the viewer is told how the game will be played, and the contestants set out with a strategy which they think, based on the construct of the game, will lead them to win. (Example: The website says that tribal immunity happens until tribes merge in 7th episode, then individual immunuity... so, a logical strategy would be to form bonds within your team to keep your team winning team immunity, and to keep you from being booted.) You create an alliance, successfully take power of the team, and have a good shot at winning.
b. Then, halfway into the game, you are thrown some unannounced twist into the game which renders your strategy fatal. Suddenly, being in an alliance in a team doesn't even matter at all. In fact, it completely screws you, because your new team is afraid of you due to your strength. And instead of winning, you are immediately booted because of this change. Everything you have done is wasted.
Would this seem fair to anyone? To the audience? To the contestants? I think not. And I think it would piss a lot of viewers off.
This would SCREAM tampering, as it would appear to be the producers in effect choosing who wins and who loses.
IM STILL NOT BUYING ANY KIND OF PERMANENT SWAP IN TRIBE MEMBERS.
