I think that your arguments about different training needs for the B and C would have been very valid if the B could land vertically as a Harrier does. My understanding is that to be able to bring back unused weapons that the B will have to do a rolling landing.
I would have thought that the skills needed to master a rolling landing on a pitching carrier deck at night relying on the aircraft's brakes to stop, whilst a different skill set from those of a run of the mill naval aviator, would mitigate against the swing squadron concept.
Quite prepared to be corrected on my understanding..
