Light carriers under Washington limits

If light carriers had a separate Washington Treaty category, would the Royal Navy build larger but fewer standard carriers?

Yes; he suggests the Royal Navy could aim around 27,000 tons for fleet carriers while using 15,000-ton light carriers to increase overall coverage.

Treaty categories can act as a force-structure tool. Fleet carriers could stay near the upper treaty size while 15,000-ton light carriers add numbers. The payoff for the Royal Navy is coverage: more carriers can spread aviation across imperial and fleet commitments.
