I like your simplification of the pythagorean tuning algorithm and would run with that if explaining this again. On your first point I think there exists a vst that tunes each chord you play to be as consonant as possible. A related side project I had was to take a midi file and through optimization specific to that file, define a scale to play it on which is makes a trade-off between 1. making the original tune as recognizable as possible, 2. as different to a western scale as possible, 3. as consonant as possible. I've yet to make it sound good!
