An attempt at the fast battleship version of the Super Lion

I thought that I would make another attempt to do the Super Lion as a fast battleship in Springsharp. I have this rather large set of dimensions mind, and the ship demands the use of lightweight machinery (31.7 SHP/ton, which is asking a lot for 1912). You may or may not recall that this is a 30-knot ship with 10-15in guns. The fast battleship version needs a 13in lower belt. This is the photo of the Super Lion with the large dimensions:
