I understand and support the "official studio" rule if that's what you decide to go with. Opening the floodgates for just any fan edits is indeed a slippery slope.
At the same time, I think an exception should be made for harmy's Despecialized Editions of Star Wars. These aren't fan edits in the sense that they're doing something new with the material. Harmyy is simply re-creating the
original theatrical versions of the Star Wars trilogy since George Lucas refused to ever release them on Blu-ray. The only "official" HD versions of the films are bastardized with the horrendous CG footage from the late 90's Special Edition releases — and have even been further tampered with in the Blu-rays to retcon characters from the prequel trilogy.
For example, if you watch the final scene of Return of the Jedi on Blu-ray you'll see this:
The Despecialized Editions are simply trying to preserve the Star Wars films as they were originally released. It has been a massive undertaking even getting to where they're at and the work still isn't done. These projects have gone "mainstream" for all intents and purposes, they're not niche little fan fiction.

etc.
These "edits" are just the original theatrical releases of the films.
Regardless, the rules need to be hashed out. And even if some special releases are referred to in the name of the movie —
no media center software takes this into consideration. Only the *ORIGINAL* theatrical release date is parsed and there is only one version of a given film in the database. This is true for every version of Kodi (XBMC) as well as Plex. It doesn't matter of there's a separate entry on TMDB for Prometheus if the media center never even looks there.
The fact of the matter is that in the particular case of Star Wars, an extremely large number of the XBMC/Plex userbase will be interested in having these versions of the films in their library. Regardless of what you "envision" for your website, there will be high demand for this. Higher than any other fan edit that currently exists or will ever exist in the future. This is Star Wars for fuck's sake, and the average XBMC user is interested in having HD versions of the films he originally fell in love with as a child.
The solution to this is to have two different "levels of priority" for posters. For example, when a moderator approves a poster he or she could flag it to not be voteable or whatever. An "extra" poster, basically. A poster that would only show up in the media center if a user decided to change it themself and would never be automatically downloaded. Since none of the media centers treat different editions as different films (and never will since that would be a nightmare for casual end-users) this is the only way to address your concerns while still allowing what should obviously be allowed.
...and I do still maintain that it's obvious. I'm sorry if you're offended by my tone, but I'm not wrong.
