I'm not sure if it would be practical to implement, but I think it would be cool to mix the Form the Ranks mod with SWC. The ability to create squads would be awesome.
Another thing would be nice: clone troopers should use blue blaster bolts, not red ones. This would take, like, 5 minutes or less to change, so I'm kindly asking you to do so.
Add the deathstar and it/its scenesI suggest to make the unfinished Second Deathstar, so that it's more historical accurate, if Luke is a lord then the First Death Star is destroyed. I've seen a ingame model, and it looks like the first deathstar, it would be great if this was fixed.
A new hope armour? The stormtrooper armour is the same in IV, V and VI.
