Considering Lando has already been in place, I don’t know that the Falcon would be necessary to show anyway. Luke’s X-wing would probably be enough.

I hope you will use the original name for the Imperial capital: Had Abbadon. The only place you could put it is in the crawl, however.

If the Rebels lose, what will be the victory? Considering this would clearly be the “end” of this version of the Star Wars saga, there would need to be some redeeming, happy ending I think. Han dies, the Rebels lose, Vader is redeemed but dies, and the Emperor dies…I’m not sure it’s enough of a victory. Will the non-Death Star space station be destroyed as well in spite of the lost battle? It just seems that the Rebels need some sort of consolation prize to me.
