It would be interesting to me at least.  It is a natural extension to
the software-tuning idea, and it would have many applications, as you
can give notes individual expression, make them sensitive to other
notes, control ornaments or accompaniment figures as "macros".  It
sounds like a very good idea for extending the keyboards capacities by
computers.   Could also be applied to a piano with MIDI interface, for
"prepared piano" in a new way.   Sounds promising. 

Question: How do you realize the soft-tuning?  I assume that you do
not send a complete user-tuning for the entire keyboard each time a
retuning is requested, but rather modify each note every time it is
played.  What MIDI command do you use (a. control, b. pitchbend
(14bit), c. aftertouch?).   

Subquestions on this:  

1. In the case of a. and b. it is necessary to play notes with
separate control messages on separate channels.  That is no problem if
you record each voice on a separate channel with a sequencer, but
automatic realtime of polyphonic keyboard input could be tricky.  What
is your approach?

2. Given that the modulating command cannot be sent simultaneously
with the note-on command, how well does the synthesizer respond to the
modulation?  (From your description I gather that there are no
problems like bent notes or "glitches", or unevennes of volume, but I
have experienced such problems on an EMU Proteus).
