Possible loopholes:
 * 1) The pairs that would enter the merge would automatically have his/her partners' jury vote no matter what. Even if the partner got betrayed, their relationship outside of the game would be enough to overshadow the in-game conflict that they had.
 * 2) There's a contradiction between the "Pairs Survivor" concept and the Survivor Rulebook. The rulebook states you cannot conspire to split winnings. Having pairs related by blood in the mix pretty much violates the rules. Furthermore, though there can be only one winner, the prize money that both members get are most likely to be shared, which kinda defeats the game's concept.

In closure, I'd give it a chance, but my expectations are not that high.
