While your idea is solid and I support it. I highly doubt the guard systems will be removed. Too many people think they need an entire system to train in, own, or further their factions role play.
A single guard station (or multiple) would allow them to do two of the three. We have Conn for a reason, and you can easily train around some of the more remote areas.
