I’d say, apply a global color correction to the new scan (or, if it works, use the shot-by-shot settings you’ve used for the Silverscreen version), make it GOUT-synced and release a Grindhouse version of it. People really love the Grindhouse releases of both Empire and Jedi, so to get something out the door quickly (and hold people over until you finish another fully cleaned up version), this might be worth it.
This. Harmy’s ROTJ Grindhouse is great even with the scratches. Plus, the quality is good enough that people could use that material as the basis for their own project and do their own cleanup if they wanted to.
