There have been a couple attempts, the term is "adaptive pure intonation." Check out the list at https://en.xen.wiki/w/Adaptive_just_intonation https://en.xen.wiki/w/Adaptive_just_intonation . Also want to plug my own project, Pivotuner: https://www.dmitrivolkov.com/projects/pivotuner/ https://www.dmitrivolkov.com/projects/pivotuner/ . I believe it gives more flexibility and control to the performer than the others on that list. It's not publicly released yet (hopefully soon), but (anyone) feel free to email me if you're curious to try it out!
