A couple things, more space or Snow battle is always good. yeah!

I'm really intrigged by the idea of changeing Vader's line from "Obi-Wan once thought..." To "Your Mother once thought as you do". I really like this idea.

I do not however like any ideas that completely disregard the EU. So no killing Bobab Fett or blowing up the MF with Lando on board. No, no, no. This was one thing I loved about SWANHR is that ADYWAN didnt gut anything and I hope he maintains that. (removing Boba Fett Entirely from RotJ is far less objectionable...Why is he there just hanging out?)

The idea of adding a planet that the moon of Endor can orbit is a good one except for one thing. On the very first page of the RotJ Novelization is says "...Endor_a moon whose mother planet had long since died of some cataclysm and disappered into unknown realms." So no planet neccessary.
