Polyphonic aftertouch with full rebuild?

Is it possible to get polyphonic aftertouch together with the "full rebuild" option for tuning? It would be nice because currently "full rebuild" seems pretty much required if you want to use a tuning system with many more notes per octave. (Most octaves are unusable with 31 equal divisions of the octave and string tension tuning for example.)

I can get the effect pretty close with an MPE-like use of pitch bends (using my Android tablet with a custom MIDI controller application), but I'm about to get a Lumatone (https://www.lumatone.io/), and I don't think they're planning to do the MPE-like tuning thing quite yet, just arbitrary mappings of midi note numbers. (I'll be trying to see if I can get them to support the MPE approach as an option in a firmware update, since it would be convenient to not have to manage tunings on the instrument side all the time. Eventually it'll do MIDI 2.0 tuning, but nothing supports that yet.)
