Just some more input here…

Not sure if Ady has made a final decision on the sarlacc, but I think that the original, lifeless pit is as bad as the CGI beak. However, the latter could be made to work if there were any way to make it look less like a video game. Is there anything Ady might be able to do in that regard?
Similar suggestions may have already been made, but for the battle on Endor, there are two or three shots from the second Ewok TV movie, ‘The Battle for Endor’, where Ewoks fire blasters. If a high enough quality source of this footage is obtainable, it could be used to make the Ewoks look a bit more like a serious threat to the stormtroopers.
Lastly, also for Endor, has Ady considered including an extra to play the “Nik Sant” character that Dave Filoni and many fans want to retcon as Rex from ‘Rebels’? (This guy: https://goo.gl/images/Z42jTU ) Perhaps if a good lookalike can be found, some of the rebel soldiers could refer to him as “Rex” during the battle?
