How large would light cruisers become?

What would a light cruiser look like under this alternative treaty system?

Likely up to about 10,000 tons and 6.1-inch guns, with an 8,000-ton Royal Navy norm and room for much stronger all-gun designs at the ceiling.

The suggested light-cruiser ceiling is roughly 10,000 tons with guns no larger than 6.1 inches. Ordinary Royal Navy ships might settle near 8,000 tons, while the treaty maximum permits much heavier designs. A 10,000-ton vessel could carry four triple turrets and resemble a powerful Town-class concept much earlier. Keeping the 9.2-inch station cruiser in a separate regulated category preserves a meaningful distinction in mission and force structure.
