What a 14-inch gun limit without a tonnage limit encourages

What would navies build if a treaty limited guns to 14 inches but imposed no ship-tonnage limit?

They would build very large ships with many guns, such as a British twenty-gun battleship using five quadruple 14-inch turrets.

The treaty rule becomes an invitation to multiply barrels rather than restrain the ship. A British battleship could carry five quadruple turrets, three forward and two aft, for a twenty-gun main battery. A twenty-four-gun version is also conceivable if displacement remains unrestricted. Designers can optimize against the exact wording of a treaty and preserve enormous broadside weight despite a caliber ceiling.
