12x14" is not going to work on that hull. If you want 12x14" guns, look at the Fuso and Ise classes, as they are of the right size for that number of guns of that size.
Will 12x10" work here?
The design is also way too old for a battleship designed in 1928-29.
Tristan wants to remake its background, so, I will temporary remove the ship.
