Now my Whiffing creative juices are flowing , I think I need to pick up another (Hasegawa) TA-4 and give your idea a go (with my mods that is ), but use Volkodav's idea of defensive detachments based on catapult equipped battleships, cruisers etc, could use codes and markings etc from A-4 air defense detachments that were assigned to the smaller USN ASW equipped Essex class carriers during the 1960's.
I'm thinking the F-14 would best stay with twin floats, you'd need a very big single float and you'd still need outrigger floats for stability on the water.
With a fully faired float you could make the weapons bay open from the sides of the fuselage under the wing and it could still be an ambhib. with landing/beaching gear in the extended float as well as carrying more fuel. :)
central single floats are elegant indeed : there is more to come, soon, here !
