Whatever the RP explanation for Zoners not being allowed to dock in house space, I doubt the system changing hands is going to change it. Leeds is still part of Bretonia geographically, and (regardless of control) house space. "Bretonia and house space" isn't quite the same as "Bretonian house space" but rules-wise it is.
Kansas is in the house list for its connection to Humboldt mostly.
Tottori, not quite so important rules-wise but is definitely Kusari inRP.
The Hogosha-Xeno conflict is from vanilla, you are free to not acknowledge it though.
Gallia is structured differently from other houses, treating them as separate borderworlds, and the fact that some systems have magically re-arranged themselves from when the RP was written made it difficult. Dauphine is heavily stated as a Border World throughout the Second Gallic Civil War story. Going by the Clermont infocard was reasonable for Core systems, but now that Lyonnais actually borders something non-Gallic and Provence is even more in the arse-end of nowhere I moved it along.
Also it is kind of balanced if you scoop out the guard systems.
