The role-play proposal asks for 30 to 32 knots, a 35-metre beam and a 15-inch belt with battleship structure in about 1918. Those requirements must be matched to marine boilers and turbines available in that year. Retaining the beam needed for the guns while seeking higher speed makes hull length and proportions part of the problem. An assumed 850 psi boiler is challenged because a stationary installation does not establish a suitable marine equivalent. The comparison with lengthening a Queen Elizabeth design illustrates how hull geometry and machinery must be considered together.

Testing a 1918 fast-battleship proposal against available machinery
A role-play design demanding 30 to 32 knots and heavy protection is challenged on hull proportions and the machinery available in 1918.
