If Mogador set the London destroyer-leader limit

What if the Mogador class had established the destroyer tonnage limits at the London Naval Treaty?

A roughly 2,500-ton leader limit would likely pull ordinary destroyers upward and give ships such as the Tribal class room for heavier torpedo and dual-purpose gun armament.

A Mogador-sized ceiling could define destroyer leaders around 2,500 tons and raise the ordinary destroyer allowance toward 2,000 tons. On a Tribal-class design, the extra displacement could support more torpedo tubes and possibly the desired 4.5-inch dual-purpose battery, making the whole Royal Navy destroyer lineage from 1930 onward markedly more capable.
