The only question I have is on the torpedoes you state in your Data. 6x21", but I cant see a triple mounting. I can see a couple of 'fixed beam' doors under the aft mk37, should there be another door there?
As to the drawing, I am always a fan of using US resources to re-arm British ships. The 5"/38 is more acceptable to Admiralty on cruisers than the 4" or 4.5" which may actually be better AA guns but as always the "bigger is better" mindset is hard to get past.
The Hawkins AA proposal has certainly produced some interesting designs. It is probably up to Smurf with his greater knowledge of cruiser plans of the time to pronounce judgement on what might have been 'never-were' drawings for addition to the archive. The rest will just become footnotes in history.
Of the drawings I have done for this thread these are the two that I would select as never-weres, plus BCRenowns V2 of the US rearmament.
5.25" version with 6 turrets.
4.5" version with eight twin turrets.
BCRenowns 5" US rearmed version
