In keeping with this, I suggest adding more of the small and medium sized colony stations, mostly of a friendly alignment, with different descriptions for them, different guard-ship sets, different items for sale, etc. Stuff more like the Ag station, only with different themes. These stations would either not be part of the commonwealth, or only loosely affiliated with them.
I don't have any concrete ideas for specific types at the moment, but I'll just bet somebody else has some they're just dying to share.
