A little far away from Star Wars, but …

Slipstream (1989) laserdiscs (see the Slipstream thread, end of page 3), UK pan/scan & JP widescreen, have problems. To fix them, can your process take the pan/scan picture as a reference and alter the widescreen to matching colors? The caveat is that the widescreen’s blue channel has been mangled beyond my normal corrective measures.

BTW, if you can process just a frame to check the effectiveness with these captures, here are the fullsized Slipstream JP & Slipstream UK laserdisc snapshots. Thanks!
Also, would your technique work on the B&W R-G-B separations for the best(?) color matching result?

JP – orig / Red / Green / Blue . . . . . . UK – orig / Red / Green / Blue
