That has issues with getting in and out. It's possible to solve everyhing, like have a zero-gravity "hub" in the middle, reachable from the habs by lift climbing the ropes. Or have pulleys reconfiguring whole habs as needed. But again anything moving in space and with life support sounds like massive r&d effort.
