The scenario I'm talking about is not synthesising a RAW file from scratch, but being able to freely edit it and save the result back into a RAW file that looks "original". I don't think you've made any statements that indicate that doing that would be complex.
Again, this is not about faking a RAW file from scratch, just being able to edit it in place.
One potential complication just occurred to me. If, (IFF!) each sensor site has a somewhat unique non-linearity in any way, you can't just go around in the image and change "pixels". You have to adjust them in a way that would not change the patterns normal to that camera for that sensor site and for neighboring sensor sites which could have been affected by the same light.
