A quick suggestion for ROTJ:R, maybe throw in a reference to Thrawn in the background displays or see if you can add the Rebel’s Ghost ship in the Battle of Endor. It would be quite a treat for fans of Star Wars Rebels. ESB:R is a masterpiece. Wishing you all the best on ROTJ:R Ady!
Ady really isn’t into adding things from the EU, and I personally wouldn’t want him to step on the new canon by assuming either of those things survive to RotJ!
Sabine mentions at the end of Rebels that Hera fought in the Battle of Endor & Ghost is in Rise of Skywalker-just sayin’.
