An attempt at William Hovgaard's "Battleship-Cruiser" in 1903

I wanted to see what could be done with using 1903 technology to implement William Hovgaard's Battleship-Cruiser concept. He wanted a fast battleship that might sacrifice a few guns to still have heavy armour and a high speed. I was able to have 8-12in/45, 12-6in QF guns, an 10in belt, and 24 knots speed. To do that with reciprocating engines and coal-fired boilers demands a very large ship. My Springsharp design is 25,911 tons standard. This is the Springsharp report:
