How Neptune might have survived into the Falklands era

Could an unbuilt Neptune-class cruiser have affected the postwar Royal Navy or survived to the Falklands War?

Possibly: its size and layout offered more modernization room than the Tigers, including helicopter conversion while retaining substantial forward gun power.

In this counterfactual, completed Neptunes might have entered service around 1950 and proved easier to modernize than the Tiger class. A plausible refit could exchange after guns for helicopters while retaining forward quadruple six-inch mounts. Such ships would have offered the postwar Royal Navy considerable visible capability, though the assessment remains speculative.
