Five Lexington-scale conversions transform Royal Navy carrier strength

How would the Second World War change if every Royal Navy carrier conversion became a Lexington-style carrier?

The Royal Navy would gain five powerful strike carriers with substantially larger air groups, producing a very different carrier war.

The counterfactual replaces five British carrier conversions with Lexington-style ships using British weapons, equipment, and aircraft. The resulting increase in air-group capacity would be a major improvement even though the vessels would not follow the later British armored-carrier pattern. Argus, Furious, and Eagle in particular become much more capable wartime assets.
