I have a few remarks about the addition of lattice masts on the postwar units. They share the same issue of the Yamato refit that appeared on Man in the High Castle on which you might have inspired from.
The two main rangefiners are 15m (forward) and 10m (aft) pieces, so they need at least a bit of clearence over that in order to properly rotate around, and at the moment neither your forward and aft one can do that, the aft set has even more equipment in the way than just the mast.
Here is an example, a Cruiser form my AU. Not a Battleship but still a valid example I think. The rangefinders are 10m ones, see how distanced the masts are from them?
I also suspect the aft rack of life rafts might get melted the moment one of the missiles is fired.
