I think prokofiev's etude op.2 no.1 could be a fairly challenging double note etude. For the score :https://www.piano.ru/scores/prokofiev/prok-op2-1.pdfFor a record :https://www.dariarabotkina.com/Music/Dasha-Kazan-1-11-04-Prokofiev%20Etude1.mp3I don't know your abilities right now, but I think it should be in your abilities right now!
I have it and will email a copy to you. Unfortunately I haven't dared to learn it yet. Can comfortably manage no. 4, and currently working on no. 6 (though it's nowhere near "presto" yet !!)Gregory
