While I like the idea of a large continent with lots of realms, I have to say that I don't like the merging idea. It would be fiendishly complex process, prone to an insane amount of bugs. It would also require the addition of all kinds of crazy regional restrictions due to council members, lordships, duchies, and other such things.
And on top of all that, you'd completely upset the political landscape of every island. At this point, that would be the death of the game. We'd be better off just closing the world, and opening BattleMaster 2.0.
