The best option for a Joy Ride experience OT is to just make a whole new version I agree.
But the original film needs to be restored first and how many times can you re-invent an old movie to alter it to try and make it something else, perhaps it would make it better perhaps it would end up worse.
I would like to see the old special effects crew (where possible) that worked on the OT to come back and actually make new shots for a new version but in the same vein as that exists in the movie with models and some 3d mattes perhaps but done using today's technology but made to look of the time. Imagine miniatures shot lord of the rings style but in the Star Wars universe, that is what I am talking about
And also it would be nice if they included some of the deleted scenes or planned scenes that were never completed at the time that would actually add to the experience perhaps (although it's not too much or too many) rather than some of the special editions additions that detracted from the film in some instances.
I mean like imagine Cloud City, Endor Platform, Yavin Base as a Miniature shot like Minas Tirith or Orthanc from LOTR, It would be Amazing.
