Capital-ship design without wartime shortcuts

How would ship design change if the war were delayed without abandoning the dreadnought concept?

Design would advance in more deliberate generations, with fast battleships dominant and surviving battlecruisers pushed toward about 35-36 knots.

The absence of emergency construction encourages more deliberate development rather than the abrupt wartime sequence known from history. Battlecruisers either disappear into the fast-battleship type or become much faster specialists able to maintain their traditional seven-knot tactical advantage.
