A delayed Washington Treaty and the capital-ship race

How might a Washington Naval Treaty delayed until 1924 have changed capital-ship construction?

A later treaty would face sunk costs in larger ships already built or far advanced, making its limits harder to impose and potentially changing which ships survived.

A treaty delayed from 1922 to 1924 might have preserved Lexington-class battlecruisers and perhaps a British 18-inch ship already close to completion. Once navies had spent heavily on new ships, governments would have much less reason to accept their immediate scrapping. A Royal Navy already holding G3s or N3s would resist treaty limits that instantly made most of its newest construction illegal. The timing could produce larger or looser limits and make agreement much harder.
