They're supposed to take over from the Russian block anyway. The eventual plan is apparently to build their 4-5 modules out, and once ISS is to be decommissioned, they'll grab the Japanese lab module and the candarms, then punt what's left of the old station loose.
Wasn't part of the CRS requirement that the dragon 2 be able to integrate onto centaur, and the starliner onto falcon so that a launch vehicle loss wouldn't ground either system? That was one of the big selling points I remember being flogged on with Boeing getting so much money, that it would mean redundancy with both vehicles AND launch systems?
Thanks for sending me down that rabbit hole...
What I've found so far is that it was not a
requirement per se, but in Alan Lindenmoyer's (Commercial Crew Program director) presentation announcing the candidates back in 2010, Boeing advertised that Starliner would be compatible with Atlas V, Delta IV, and Falcon 9. Crew Dragon has never been advertised as having the ability to fly on a Centaur. I've seen nothing that indicates any work has been done at all regarding being able to launch Starliner on an F9, and it would probably take 2 years (at least) of solid design and analysis work to make it so. You're going to need a new adapter at a minimum.
Honestly, it wouldn't surprise me if SpaceX hasn't had a couple guys at least looking at this (it's exactly the kind of flex Elon loves to make), but my guess is we'll never see it happen.
