I was a big fan of the work done on ANH:R and ESB:R (except for reverting Bobbas voice, and I will fight to the death over that 😄) and am looking forward to the ANH:R:R a lot (though I’d rather the SDs and DS plans are left as they are and any hypothetical RO:R fan edit changes them to match ANH:R).

To me RotJ is the film that needs an edit the most (well excluding TPM and AotC), more so than either TFA or RotS even, but I think the things it needs the most are probably out of Adywans remit of revisited edits (for reference it’s the movement of Yodas death and Lukes lightsabre construction on Degoba and his telepathic convo with Vader as well as a restored subplot of the Moff who’s name I can’t spell, and the removal of Bobba from the film).

However I’d like to throw out a few ideas, mostly already suggested…

Colour correction and lightsabre/blaster fixing (goes without saying really)
New matts throughout
Removal of both musical numbers from Jabbas Palace (or make the origional backing music)
Keep the Sarlaacs beak and enhance it more
Change the Tydirium to the Zeta-class (the exact class from RO)
Change the Emperors ship to a Delta-class to distinguish it from Needa and Vaders ships
Maybe change the AT-AT on Endor (that’s not present in combat) into the RO cargo version
More views of the DSII
The large sized interdictor from Rebels in the background (or maybe two)
Restore the deleted scene of the Rebel general with the silly shirt in command of one of the Mon Cal ships that gets vapourised
Shield glow over the moon
Correct all Imperial ranks
A wider verity of ships (i.e. more ships larger than the CR-90s) in the space battle for both sides
Something I’ve seen mocked up by AggeIw (https://aggeiw.deviantart.com/art/Give-me-a-Hand-216238791)
Add a window to the DSII bridge
Keep Vaders removed eyebrows and let a Rebels faneditor remove them there.
B-Wings, U-Wings (in the hangers not in combat), TIE Defenders
By the time the edit is progressing Rebels will have aired its final series meaning we’ll know for certain if it is indeed Rex on Endor. If it is either a tannoy announcement for him or some short bits of dialogue lifted from Rebels would be nice
As many ships and pilots as you can cram into the space battle, it’s the final battle of the series it needs to exceed Scarif and Coruscant despite the smaller Rebel fleet
Anything you can do to the ground battle to make it better is appreciated in any way providing it downplays the Ewoks as much as possible and possibly ups the Imperial competence down there. However the space battle and Lukes battle are the main focus not the ground one
Keep the ending celebrations but tweak them so it’s a bit less immediate
Retcon Wedges Scottish accent into ANH:R:R and into the Blue-Ray of ESB:R
The views outside of the Emperors window should show the battle and not a static image of 4 SDs with green flashes on them
Sort out the Rancor so it’s more natural in its movements
Replace Haydon with Matt Lanter

Like I say, most have already been suggested but I thought I’d throw in mine as well.
