well, for the band arrangement, I split it up into two different parts. I thought about the possibility to play it, and it just wasn't very likely. While the main two parts are going on at the right half of the piano, there are arpeggios going on on the left half. I suppose if I left the lowest notes out, it might work, but those are important.
Besides, it's a high school band that I wrote this for. I'm only 15, and I'm not that talented of a player.
