Battlecruiser version of the Super Queen Victoria class

I was thinking of the Kii and Owari, specifically, when I thought I would try a battlecruiser version of the Super Queen Victoria class. Of course, the Kii and Owari were fast battleships, but they would have been very similar to the Amagi class battlecruisers. Perhaps because my ships seem to be better protected, they are much larger. I also suspect that is because of the vagaries of Springsharp. If we had used lighter machinery, the result would be more in line with the prototype. This is the Springsharp report:
