@Harmy:
Of course it is possible, like anything with avisynth! But believe me, after so much analyzing of these movies, I can tell you those jaggies are everywhere. I just chose that R2 shot kind of randomly.
Even if it hadn't been hard to do what you're saying, it would create inconsistency since it doesn't only remove jaggies in those shots but also grain and detail. Even in the R2 shot, detail is removed when jaggies is. The current script will create a consistent result with enough jaggies removed to be much more watchable, and just wait until you see what the dirt remover does!
Anyway, here comes another little teaser. A couple random shots from ESB and ROTJ, unprocessed GOUT compared to the script.
