I must admit I don't know a lot about King - but having read your posts, it seems realistic to think he will not be promoted in FFO like he was in OTL.
I mean, his promotion was mainly the result of a catastrophic situation. In FFO, Stark's role in Europe could be played by a British admiral with a French deputy (under Eisenhower authority, of course). So Stark stays where he is and King too, barking for more allied ships in the PTO ("Hey, Stark, those bloody Brits and their frog-eating friends have a LOT of ships staying idle in Europe, LOTS of BB in Scapa, a.s.o.... Tell them to send them in the Pacific, $*&"'' !!!").

This said, I'm not sure the consequences will be very important ?
