Ahoj!
Mike, Coles/Ericsson turrets are a bad, bad idea. Maybe you clicked in the wrong place, and you wanted turret&barbette?
That change would allow you to increase your misc. weight, so that you could carry Marconi and torpedo reloads?

     on centreline ends, majority forward
   Weight of broadside 9 lbs / 4 kg
   Shells per gun, main battery: 150
   4 - 18.0" / 457.2 mm above water torpedoes

Armour:
   - Gun armour:   Face (max)   Other gunhouse (avg)   Barbette/hoist (max)
   Main:   1.00" / 25 mm         -               -

Machinery:
   Coal fired boilers, steam turbines,
   Direct drive, 2 shafts, 13,851 shp / 10,333 Kw = 28.60 kts
   Range 2,000nm at 10.00 kts
   Bunker at max displacement = 106 tons (100% coal)
     Caution: Delicate, lightweight machinery

Complement:
   58 - 76

Cost:
   £0.066 million / $0.264 million

Distribution of weights at normal displacement:
   Armament: 1 tons, 0.2 %
   Armour: 3 tons, 0.4 %
      - Belts: 0 tons, 0.0 %
      - Torpedo bulkhead: 0 tons, 0.0 %
      - Armament: 3 tons, 0.4 %
      - Armour Deck: 0 tons, 0.0 %
      - Conning Tower: 0 tons, 0.0 %
   Machinery: 338 tons, 58.7 %
   Hull, fittings & equipment: 159 tons, 27.6 %
   Fuel, ammunition & stores: 71 tons, 12.4 %
   Miscellaneous weights: 4 tons, 0.7 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     132 lbs / 60 Kg = 41.7 x 1.9 " / 47 mm shells or 0.2 torpedoes
   Stability (Unstable if below 1.00): 1.20
   Metacentric height 0.7 ft / 0.2 m
   Roll period: 10.9 seconds
   Steadiness   - As gun platform (Average = 50 %): 72 %
         - Recoil effect (Restricted arc if above 1.00): 0.03
   Seaboat quality  (Average = 1.00): 1.03

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.400
   Length to Beam Ratio: 10.00 : 1
   'Natural speed' for length: 14.83 kts
   Power going to wave formation at top speed: 70 %
   Trim (Max stability = 0, Max steadiness = 100): 70
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      16.32 ft / 4.97 m
      - Forecastle (20 %):   10.38 ft / 3.16 m
      - Mid (50 %):      10.38 ft / 3.16 m
      - Quarterdeck (15 %):   10.38 ft / 3.16 m
      - Stern:      10.38 ft / 3.16 m
      - Average freeboard:   10.86 ft / 3.31 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 191.8 %
      - Above water (accommodation/working, high = better): 59.1 %
   Waterplane Area: 2,979 Square feet or 277 Square metres
   Displacement factor (Displacement / loading): 25 %
   Structure weight / hull surface area: 22 lbs/sq ft or 109 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 3.39
      - Overall: 0.61
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is cramped
   Ship has slow, easy roll, a good, steady gun platform
