That's no different from closing the EC and opening another island that has the same map. And for why we're not closing EC, see above re: "Tom's favourite island."
Aside the fact that i don't see this as a pretty valid reason, I still believe it would be better and give a more fair change to players that lose their main island. Everyone also knows that people does not stick together and do a mass move to one realm(since that would also be considering as making a clan).
In the end closing the other islands and having players move to EC with no compensation or anything at all would just be a way to punish them and show that the history and work they did in other islands is basically useless.
