   Excellent idea !
   Requires linear frequency offset for the sound source (to compensate
   the FS for the fundamental).
   I want to try this. What's a good amount of FS for such experiments ?

I don't know, but I would guess around 10 Hz or so.

Since piano stretch tuning exists because of the non-integral
harmonics, perhaps a stretch tuning chart would help.  A quick web
search found this:
