My immediate thoughts. If only pianos were typically positioned in the same spot for a long time, allowing to do those measurements once and hang the speakers appropriately from the ceiling. Or make a speaker array in the base and do all sorts of spacial Fourier/phased array madness.

I guess if you want a gimmick piano you can have it.

It’s a concept piece. Gimmicks (or, more charitably, exploring out-there ideas) are the whole point.
