I just wanted to clear up that the F35 does not actually hang any missiles on its weapons bay doors, in case my earlier, poorly worded post was the cause of the confusion.
That F35 have a pair of normal launch rails, which pivots down when the weapons bays open, to create the necessary clearance for weapons deeper in the bay to be released.
It just appears that a pair of missiles are mounted on the inside of the weapons bay doors when that is not the case.
It might be a possible option for the FC-31 or the F-35, I'm not sure Wolfie, I think they anticipate increasing F-35 weapons bay carriage from 4 to 6, correct me if I'm wrong Bub!
