If I can predict the lottery numbers, you'll be able to spot my house by the swinging door and tyre tracks...But if you give me a few million £ I'll tell you your fortune !
The argument that the RAF could cover things was always spurious, to put it kindly.
I'm not too sure about transferring kit from FA2 to II+, but if the Blue Vixen could have been installed ( I think a larger radome would be required, a la FA2, along with a lot of other systems; the cooling setup was quite something ) that would have been a good move, but the work and cost of developing a whole new aircraft.
Throughout it's short history the RAF has always tried to snuff out the Fleet Air Arm; which in turn has come to the fore when most needed.
I'm not a member of either, I just read history...
