My preffered ending to Star Wars force unleashed. Anyone else?

I beat the game on the Dark Side and on the Jedi Side. What I would like to see is Darth Vader and Sky killer kill the emperor and perhaps Vader turning into the good guy like he really is. I didn't like seeing the way vader was betraying his apprentice. I thought maybe he would try to make him like the son he lost. I think when Vader said that he wanted to kill the Emperor , but not with skykiller, he knew he had a real son out there and that is who he wanted to kill the emperor with. Anyhow, Darth Vader is my favorite character and he is really a good guy, he has just been clouded by the emperor and the Dark side.
