Fitting three superfiring twin turrets forward on a battleship

How much beam and displacement would a battleship need for three superfiring twin turrets all forward?

For twin 14-inch guns, roughly a 35,000-ton King George V-sized hull could theoretically support the arrangement, with growth needed for better performance.

A King George V-sized design could theoretically carry three superfiring twin 14-inch turrets forward at about 35,000 tons. The historical class already carried substantial beam to accommodate quadruple turrets, so smaller twins ease the transverse requirement. Higher speed or other performance improvements would still add weight and could force the design to grow.
