Thought I would throw my hat into the ring with a modified never-were design.
Essex Class
HMS Essex, in 1933
For the two heavy cruisers to follow the Northumberland sub-class of the Counties, their Lordships demanded increased fighting power. Using savings in construction had meant the previous ships had completed light and progressively fittings had been added. It was thought possible to fit an extra 8in turret to increase the broadside weight. The quarterdeck was lowered to save weight and the extra turret fitted behind 'A' and 'B' turrets. An improved tower superstructure, based on that of those of the capital ships, was also fitted to improve the bridge spaces.
The design was approved and HMS Essex and Durham were laid down in 1930. Both luckily were spared from the spending cuts as the Great Depression began to bite and were commissioned in June and September 1933 respectively.
