I watched it, and its solution is not that bad at all; but I would try to colourize it instead. And, if it does not work really well, add something like the red alarm he added in a Tantive scene, to mask the recolor, but leaving it behind somehow. What do you think?

Russian Despecialized Extended editions: they simply cut&paste (sometimes badly) deleted scenes, untouched, into the Despecialized edition… no color correction, no cleaning, no music added, nothing… there are better versions around, like the previous mentioned Wae Of The Star I and II - I may say that I do not agree with some chosen shots and music tracks, but overall they are fantastic edits!
