I feel a piano isn't the best instrument to play this piece. Even a Bösendorfer would mix up the notes, and a Steinway or Kawai horribly so. Plus the difficulty for the pianist.
You could split the music among a
cymbalum (cimbalom, tsimbal etc) and its usual colleagues (violins, cello, pizz bass, pan flute, possibly more).
speedy example
Your piece would be very playable on a cymbalum and would sound better than on a piano.
I hope such groups would enjoy your piece, which can become standard Gypsy music. Possibly they would play it their way, not exactly strictly completely literally as you wrote, who knows.
The
harp can also play very fast successions of notes, but not complex combination like a piano does, so it would need some adaptation of the score, and possibly ancillary instruments.
A
violin or an accordion play that speed easily but not with double stops, so again, it would need some score adaptation.
My impression is that you would be played very rarely by pianists with the score as is, while a transcription for small groups could have success.
For instance
Rusanda Panfili and her friends play varied music and they do have an Internet and real-life audience
based in Vienna, with at least the violin, accordion and piano that can play a voice of your score at this tempo.
