"Obscure Zone" would be cool! Short and awesome. I think it is Satsuki's theme? Besides that, there is always the other metal-style Melty Blood track - "Nightmare Teller", but I imagine it is hard to come up with something for that, since it is so fast and not very symphonic for the most part. I'm surprised you haven't done Blazblue's "Gluttony Fang" yet, since that's the series' most popular track according to the official poll from 2 years ago (the top 10 were Gluttony Fang, Lust Sin, Shinsou, Must Die, Awakening The Chaos, in the Shadows, Condemnation Wings, Silent Scream, Six Heroes and Rebellion, in that order). There was also a new poll recently on twitter by "Daily_FG_Music".
I would be interested to see what you could do with “The Fog” from P4 since it’s a relatively simple melody and there’s a decent amount of room for improvisation and even a possibility to make a complete style change despite it being mostly rock driven.
