Then is anything even taking off from a runway along the deck of the carrier/amphib? If not, I could see that imposing some pretty radical changes on the way the ships are designed, to the point where there's not much incentive for them to even look like 20th century aircraft carriers. Because 20th century aircraft carriers are designed heavily around the constraint "we need to put a runway on a bote," and everything else follows from that constraint.

With that said, it should be noted that making a warship "shorter, thiccer" means some really significant changes to every relevant part of the engineering. This is not a trivial modification.
