My concept of the proposed British semi-Dreadnoughts

This is my concept of what the proposed ships that had 4-12in and 12-9.2in guns would have been like. Of course, this is affected by Springsharp. I am using reciprocating engines and coal-fired boilers, as this is what I would expect for them. This is the Springsharp report. To work, they come out too large:

Overall survivability and seakeeping ability:
