Sounds like good guidelines so far, Asimov’s laws of robotics are a helpful way to think of this!

Separate threads for each trilogy could help spread things out, threads for each films might be too much though. Or threads by project category (reports, discussion, etc) could work. Depends what you’d prefer to set up, RogueLeader.

I have a few suggestions that I’ll throw into the ring here:

Give Mace Windu a blue lightsaber (I think this has already been done for ep2 by Jackpumpkinhead).
Relation between Obi-Wan and R2 (PT and ep4): cut “I don’t seem to remember ever owning a droid” in ep4. Apart from this line it doesn’t bother me too much, Obi-Wan is deceiving Luke in general and it’d be too difficult to remove all scenes with R2 and Obi-Wan in the PT.
Two Death Stars in the OT: This seems to me like the major contradiction within the OT. If Lucas knew he was going to continue past ep4 then the Death Star wouldn’t have been destroyed in that film, but editing the final battle to avoid this would be a major (and likely problematic) change.
The incest subplot (Han and Luke being jealous of each other throughout the OT, and the kiss between Leia and Luke on Hoth): shouldn’t be too difficult to cut, and makes Leia’s comments in ep6 less weird. Also removes some of Han’s more annoying bits in ep6.
Vader’s reference to Obi-Wan in ep6: where he says to Luke “Obi-Wan once thought as you do”, as in ep3 Padme tries to turn Anakin back from the dark side. Could simply cut the line?
Clone Army retcon in ep7: as lines by both Hux and Finn state that the stormtroopers are no longer clones. I know this is also in parts of the EU, but if the troopers aren’t clones anymore then the whole Kamino investigation subplot of ep2 is a bit of a waste of time.

Dom, you make a good point about the feasibility of the project 😕 though even if it does end up being a collective resource that would still be useful. If this becomes the revised aim of the project, then perhaps it would be better to work towards slightly more intensive changes (like making Windu’s lightsaber blue or replotting the vague reference to Sifo-Dyas), as simple dialogue cuts are easy enough to make for individual projects.
