A 22,000-ton treaty super-cruiser category

What designs might the major navies build under a 22,000-ton, 12-inch-gun cruiser allowance?

Britain would likely produce an updated Invincible-like ship with eight or nine 12-inch guns, while the new category could also reopen arguments over much larger battleship guns.

The British design would resemble a modernized Invincible, probably with three triple turrets if weight permitted. A formally accepted 12-inch super-cruiser tier would also pressure the treaty's battleship category, potentially strengthening the case for the 16.5-inch gun work inherited from the G3 program.
