I don’t think there is a similar project for empire and jedi that is in sync with the blurays.
JawsTDS did some one pass color regrades for the blurays. You might ask him for the color settings for empire and jedi and see if you can apply something similar in avisynth.
You_Too actually posted avisynth scripts way back in 2011, but the curves are now offline, and he hasn’t been around here in a while.
