How a 2,250-ton destroyer limit turns Tribals into light cruisers

What if the London Naval Treaty allowed 2,250-ton destroyers?

Britain would likely build enlarged Tribals whose gun and torpedo batteries made them light cruisers in all but name.

At 2,250 tons, the Royal Navy could enlarge the Tribal concept enough to combine eight guns with two quintuple torpedo launchers. That load would make the ship closer to the postwar Daring class than to the historical 1936 Tribal. The vessel might retain the destroyer-leader label for treaty or institutional reasons, but its combat power belongs in light-cruiser territory. Larger Commonwealth Tribals would also make actions such as Narvik still more destructive and give Canadian and Australian flotillas unusually heavy striking power.
