Why a postwar Lion still needs nine 16-inch guns

If Britain built the Lion class after the war at roughly 65,000 tons, what armament and performance would be realistic?

Something close to the planned Lion: about 62,000 tons, nine 16-inch guns, and roughly 28 knots, because six 14-inch guns would be too little for such a large ship.

The answer argues that a postwar Lion should retain the planned nine 16-inch guns and roughly 28-knot speed. A displacement around 62,000 to 65,000 tons does not itself require a radically different ship. Arming a vessel of that size with only six 14-inch guns would leave it badly undergunned for its cost and capability. The answer treats armament as part of a balanced design rather than a feature that can be reduced independently of displacement.
