I'm not in love with a lot of those ideas. Many of them will lead to rampant meta-gaming and in some cases could do serious damage to the game itself by artificially encouraging things like rebellions to be started constantly for OOC reasons, not IC ones. I mean, if you say something like "island with fewest rebellions gets sunk!" the next day you're going to have rebellions in half the realms in the game, all started for OOC meta-game reasons.
