Converting seaplane tenders could preserve fleet carriers for fleet work

What if Britain converted its seaplane tenders into small aircraft carriers before the Second World War?

They could provide global reconnaissance and anti-submarine aviation, spare fleet carriers from inappropriate duties, and possibly help preserve Courageous and Glorious.

Converting suitable tenders in 1938 or 1939 would create small aviation ships before wartime emergency programs matured. They could carry patrol and scouting aircraft for trade protection and anti-submarine work across overseas stations. That capacity might keep Courageous away from the submarine hunt on which she was lost and reduce the misuse of Glorious. The strategic benefit is cumulative: even modest carriers free scarce fleet carriers for concentrated operations and may leave Britain with more aviation strength later in the war.
