I've been thinking about doing one myself but haven't come up with a good spin on a possible arrangement (setting, style, instruments etc). I use guitars for my stuff and it might be cool to do it in a neo-doom/electric version. We'll see. Your mix is a good one, perhaps a sharper melody line and deeper bass? I especially like the stuff @ 2:30+ (the main melody thing) which is quite different from the stuff earlier in the song.
