This idea of a War does sound fun, however, before anything like this even remotely comes into play, a couple of points to consider:
People become Zoners precisely because they prefer the lack of "big brother" and government in the Houses, and don't want to get dragged into unnecessary political conflict. A Zoner House is exactly the opposite of this.
Harvesters only represent part of the Junkers, and Zoners who choose to carry out offensive operations against Harvesters represent only part of the Zoners. Don't force everyone to participate in a brawl in which they want no part.
And dusty, although there might be some competition between Junkers and Zoners, it was never all-out hostility.
