Hood-style 9.2-inch heavy cruisers

What happens if Britain builds 15,000-ton, 9.2-inch cruisers in a Hood-like layout after the First World War?

They would be armored-cruiser successors and likely drive treaty cruiser limits toward larger, more heavily armed designs.

The design would be a large replacement for the Hawkins class: a powerful, well-protected ship intended for the role once performed by armored cruisers. A class of around six would create a strong precedent for a higher Washington cruiser limit. Other powers could respond by seeking even larger ships and 10-inch guns, while Britain might retain its established 9.2-inch preference.
