Nice theory but i don't think it's possible, Lucy is a narrator type main heroine, all she does is support. And i never seen the 12 Golden keys seal evil before. The biggest problem to your theory is the gateway that will change the world as stated by Yukino is the Eclipse Gate itself which has been destroyed.
