Yes even more now. I hated them making Leia the sister. It was a lazy way to wrap up the other, and to not have to make the original second Luke trilogy. Where his sister was out there and he would confront the Emperor. Only Vader would be confronted originally in film 3. Whether it was going to be Nellith or they would have settled on another name, it was not Leia.
Leia still could have heard Luke above Cloud City and been Force sensitive, without having to be a Skywalker.
