Yeah I have had a look there thanks. Another of the things I had thought about which I noticed on that list too was adding Mara Jade to Jabba's Palace, which I have already started making mock ups for.
One thing I am stuck on though is I wanted to make it so the Emporer is still alive at the end so he would remain the villian until Episode 9 (hypothetically), however, I cannot decide how to have it so Vader dies, turns good, and Luke escapes without the Emporer dying. Any ideas?
