The huge changes like inserted CGI or new scenes and editing changes are what separates the original versions from the special editions, in my mind.
If the editing, narrative and general "retro" look remain intact, I'm fine with it.
And also, I applaud you, MeBeJedi, for crawling through this thing frame by frame and removing all the scratches and rot spots by hand. That's just crazy and shows enormous dedication and grants you the right to do anything you'd like to your version of the Trilogy.
