I was going to wait until 1924 before posting this possible design for the RN;
[SIZE=1]
Both modified from original pictures [/SIZE]
The springstyle is modified from HMS Kent found in the Springstyle libary that accompanies springsharp.

Armour deck 1.00" / 25 mm, Conning tower 1.00" / 25 mm
Torpedo bulkhead 1.00" / 25 mm
Machinery:
Oil fired boilers, steam turbines,
Geared drive, 4 shafts, 103,399 shp / 77,135 Kw = 32.50 kts
Range 10,500nm at 15.00 kts
Complement:
651 - 847
Cost:
£3.681 million / $14.725 million
Distribution of weights at normal displacement:
Armament: 354 tons, 2.5 %
Armour: 2,276 tons, 16.0 %
Belts: 1,203 tons, 8.5 %, Armament: 161 tons, 1.1 %, Armour Deck: 516 tons, 3.6 %
Conning Tower: 13 tons, 0.1 %, Torpedo bulkhead: 384 tons, 2.7 %
Machinery: 3,406 tons, 23.9 %
Hull, fittings & equipment: 5,766 tons, 40.5 %
Fuel, ammunition & stores: 2,331 tons, 16.4 %
Miscellaneous weights: 100 tons, 0.7 %
Metacentric height 4.7
Remarks:
Hull space for machinery, storage & compartmentation is cramped
Room for accommodation & workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.28
Shellfire needed to sink: 9,775 lbs / 4,434 Kg = 38.2 x 8.0 " / 203 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 1.5
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 70 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.41
Relative quality as seaboat: 1.38
Hull form characteristics:
Block coefficient: 0.436
Sharpness coefficient: 0.31
Hull speed coefficient 'M': 8.58
'Natural speed' for length: 26.08 kts
Power going to wave formation at top speed: 52 %
Trim: 51
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)
Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 136.0 %
Relative accommodation and working space: 162.7 %
(Average = 100%)
Displacement factor: 118 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 0.96
(Structure weight / hull surface area: 121 lbs / square foot or 590 Kg / square metre)
Relative longitudinal hull strength: 1.40
(for 22.50 ft / 6.86 m average freeboard, freeboard adjustment 6.25 ft)
Relative composite hull strength: 1.00
