This looks nice!

Has anyone tried just using colormatch or something similar to match it to the despecialized colors? You would obviously have some issues with the contrast because the bluray source has some black crush, but it"s worth a shot.

This release with quality colors would honestly be a great version of ESB.

My limited understanding is that those filters only work well if the sources share an aspect ratio and are stabilized; the Grindhouse edition has a lot of frame jitter and probably a different AR than the Despecialized. It could be done but it would take more work than it sounds.
