This is very good. Excellent work, Yak.
Neither this nor the current music will appeal to everyone, obviously. This has a very definite style, and it's consistent throughout the entire selection. In my opinion, that style fits very well with one interpretation of the Zero-K conceptual style; I think you described it well in your initial post: "battlefield atmosphere with a dystopic sci-fi character".
Personally, I prefer the current music, but would definitely play with this on occasion for variety. I'd love for this to be an officially supported option, but probably not the default.
I didn't audition everything, but what I did listen to was good. Exception: "10. From A Distance (edit)" does not fit with War. It might actually fit with Peace, and might give Peace that kick I think you were looking for. Otherwise, I'd drop it.
I agree with Hokomoko regarding consistency.
