And both might be doing civilian jobs at the time, in case we need the variety. That is, McCoy's exact transition from the Old Country Doctor stage of his career to starhopping was never nailed down in Prime, and Scotty referred to his years of working on "freighters" (which Starfleet shouldn't have, as the military term is "transport") and "cruisers" (which weren't starships, as Scotty next separately mentions those), plus a tenure advising Denevan miners.
Both might be in Starfleet equally well, though. But more fun could be had the other way.
