What do you think? a new take on Cuniberti's Ideal Battleship for the British Fleet

This is a good as I have done for Colonel Cuniberti's Ideal Battleship for the British Fleet. Obviously, the specifications described in his 1903 article in All the World's Fighting ships aren't achievable. This is the closes that I have come. The secret seems to be in better specifying the 12in guns. I was able to achieve the 24 knot speed with a 10in armor basis. I did have to increase the beam, draft, and displacement, but I was able to use coal-fired boilers. I did feel like I was cheating, in that I used the slider in SpringSharp to correct the recoil and stability issues. This is my favorite photoart piece of the ship:
