I like the title change thing--why not simply change your title?
He can't. He can change it from king to supreme chancellor to whatever, but he can't change what it is of. It will always state of Iashalur. I support the name change, but I agree there should be some signs of stability before allowing it to prevent the ping-ponging. I also agree it shouldn't be the exact name. There have been recreations of realms in the past, but never did they use the exact name (That I know of anyways).
