Yeah, that's kinda what I was thinking... carefully timed/computer controlled approach at tangential speed, arrive just as the outer-ring landing platform rotates under you... smash that shuttle down on the deck and hook a tailhook to a arrestor cable just like on a carrier deck. Next a telescoping docking tunnel links to your shuttle door... pressurizes... passengers debark into a small atrium and take the elevator "up" into the main ring. However--question: how does this affect the balance of the ring? You just added say 50 tons mass to the wheel in one location on the outer ring... though it brought along its own momentum at landing (near zero delta-v), does it cause the wheel as a whole to "wobble" or destabilize? Of course, there could be huge reaction wheels on the station to compensate for imparted rotations due to shuttle arrivals and departures. But it gets complicated.
