I can hope can't I? I like less pointy backgrounds when dealing with games. It gets rather dull when its all "ARRGH I WILL KILL YOU EVERY CHANCE I GET!!" and "WELL I WOULD KILL ALL OF YOU AND NEVER CONSIDER TALKING TO YOU UNLESS WHILE ITS ALSO WHILE KILLING YOU". Thats why I love Heavy Gear, the sure the north and south go at it and are at war with each other, but there is still communication, trade even. Hell, they will even ally against a greater foe if need be.
I think you misunderstood what I said--I totally think the setting you described would fit. I just meant that, given the current state of galactic politics, that kind of integrated community wouldn't be widespread. I think the official lore isn't as "pointy" as it first appears. Sure, there's some ethnocentrism on all sides, but already we've seen examples of both politics, personalities and localities blurring the usual black and white morality play. Obviously we haven't seen the book yet, but the setting seems like LEGO itself: constraining by nature, but modular enough to allow unlimited expression.
