Why the Royal Navy did not build faster Nelson repeats

Why did the Royal Navy not build faster repeats of Nelson and Rodney once the treaties fell away?

The suggested explanation is a preference for a conventional-looking battleship once the navy committed to a 14-inch quadruple-turret scheme.

A faster successor could have retained Nelson's compact arrangement and 16-inch guns. The preference here is to develop that existing design and increase its speed. One proposed explanation for abandoning it is the desire for a conventional-looking battleship, reinforced by the move toward twelve 14-inch guns in three quadruple turrets. That armament choice made another all-forward arrangement less attractive to the designers.
