As far as I know NX still uses ICC profiles. Maybe they still can be extracted using this technique:

These ICC profiles expect that the raw file has been preprocessed in some way (applying some gamma etc), RawTherapee has this coded in rawimagesource.cc, but it was a while ago since it was tested last I think, but you get the idea.
So what I would do to replicate Nikon NX look is to extract those ICC profiles, and figure out how the preprocessing is made. Then I'd generate a new ICC or DNG profile which makes the same translations but without the preprocessing (will require some coding).
