The reason for having those huge wheels in a zero gee structure would ordinarily be to provide a functional replacement for gravity: they spin, and stuff in the rims gains weight due to centrifugal force. I started to make a post why orbiting these wheels next to an asymmetric off-axis station looked risky, then realized that my Space Station Designer's badge hasn't been notarized.

I don't know what sort of coupling you had in mind but if they are not firmly attached as one system, load imbalances would leave the wheels wobbling and wandering all over. If they are attached firmly, that wobble/wander action (as well as inertia transfers from incoming vessels) could easily result in a tearing of metal and a venting of gases. Better send those wheels a safe distance away.

Beautiful map, though. I might use it anyway.
