How fifteen-gun Towns could support missile modernization

Would more fifteen-gun Town-class cruisers have been modernized after the war?

Quite possibly, because after turrets could be replaced by missiles while nine forward 6-inch guns remained useful.

The hypothetical larger gun battery gives a postwar modernization designer something substantial to trade away. Removing the after turrets would release volume and weight for missile launchers while leaving nine 6-inch guns forward. That retained battery would keep the ship credible as a gun cruiser rather than abandon its original armament almost completely. Additional modernization therefore becomes more likely, illustrating how an interwar layout can create or constrain later conversion options.
