Obviously you guys aren't breaking any radical new ground in the field of video restoration, but what you've done is taken difficult, advanced techniques, and adapted them for use in very inexpensive programs, and produced what is probably some of the most advanced amateur work ever done. If you chose to make available the details of your techniques, in video documentary form or in some sort of tutorial format, it places those techniques that you've developed in the hands of an assload of people, which all sorts of interests.
ANH is interesting in that it is essentially a rogues gallery of every sort of visual defect you can have in a film: excessive grain and dirt, scratches, color blooming, off color, matteing issues, etc etc. And all these techniques that have been developed to deal with this wide array of problems could be adapted for use in restoring huge number of films that will never be professionally restored, simply because the profit isn't there to be made.
Your starfield recovery technique could possibly be adapted to restore detail to early black and white films and historical films (WW1 & 2, Zapruder, etc). Your work with grain and dirt removal could be used to restore noir-era films that have never been restored, and been transfered to DVD with grain and scratches intact, or to restore films from the 70's and 80s that have never had a decent DVD transfer, if that.
You guys have done a hell of a lot of work, and it just seems like a shame to allow that work to be limited to fixing only 3 films, when there are so many out there that could be restored.
