A larger British heavy cruiser after 1945

Would 9.2-inch British heavy cruisers have been retained after the Second World War?

Probably, if built during the war; their presence could have reshaped the case for retaining older cruisers and battleships.

Retaining the 9.2-inch cruisers would be a fleet-wide trade-off rather than a simple addition. Wartime construction would give them a strong claim on the reduced post-war fleet. Their survival could push the older Town and County classes, and perhaps even Vanguard, out of retention plans. Keeping a heavy-cruiser capability might also lead to a more substantial successor than the Tiger class that Britain actually completed.
