If the first carrier battle became a night gunfight

How would carrier design change if the first carrier battle were decided by surface gunfire at night?

Navies might retain 4.5-, 5-, or even 6-inch carrier batteries far longer, producing ships that blend modern supercarriers with heavily armed Soviet-style concepts.

A celebrated night victory would create powerful institutional evidence that carriers must fight surface actions as well as launch aircraft. Designers could therefore accept the weight and interference of substantial gun batteries even as aviation expands. The answer is intentionally speculative, but it demonstrates how combat experience can lock navies into a particular interpretation of a new ship type.
