Capital ships without treaty restraint

Would ever-larger G3 and N3-type capital ships have made the Royal Navy ask how large battleships could become?

The Royal Navy would probably seek the next form of capital ship rather than simply ask when size must stop, with faster investment in naval aviation likely without treaty restraint.

The Royal Navy would probably seek the next useful capital-ship type rather than merely ask how large battleships could grow. British designers had repeatedly taken that approach, so a treaty-free race would encourage parallel investment in carriers as well as larger G3- and N3-type gunships. Britain had already accumulated naval-aviation experience and plans that it could develop further. The United States Navy still had to persuade Congress of the new idea, giving Britain a plausible head start in this counterfactual.
