I'm not sure that rolling the chord would be pertinent to this piece, since it's not a piece of the kind where a melody is developed alone, almost independently, supported by some chords, but on the contrary every note of the melody and the accompaniment are linked to each other as curt, sharp tones. But I promise to try, maybe it sounds good.
The idea of splitting the chord as succesive one-three notes (or three-one) is interesting, I have heard examples in some Chopin's Nocturne and it's true, it's dramatic. I'll try it too, but I hold my reservations for the same reasons above.
Thanks a lot and kind regards.
