As Damian has observed, there are plenty of examples in Bartók's piano
sonata. Other, similar situations can be found in Berg's vocal scores
of Lulu or Wozzeck, say, which both contain highly complex, polyphonal
music, and where the creators of the vocal scores took great pains to
retain the polyphony in the piano reduction.

I'm aware of that, thanks, but neither is a good solution for my use
case.
