Sure on the last point. But hypothetical pianos don't suffer the same 
practical constraints as normal pianos. ;-)

It wouldn't be difficult to have identical total string lengths for 
each trichord.

So do you (others) agree that it would be advantageous as proposed: 
"friction free" bearings, solid stable front and back lengths, and 
same total string lengths within a trichord?
