As for the Artoo problem, I've had success in little tests just in photoshop of simply going into hue and saturation and bringing down the saturation of the blues until you see the artifacts disappear. This removes the artifacts, gets artoo looking correct, and overall makes the image look alot better. This works because basically all they did to make artoo "consistent" is to to boost the blues in every shot that has artoo in it.
Great work. Not knocking your find at all, but it just goes to show how low effort the 2004 releases were.
