Double Deck the Carriers.
The Japanese built two aircraft carriers with three superimposed flight decks after WWI. It didn’t work out too well. When they were modernized in the 1930’s two of the flight decks were removed.
The IJN tried that. It didn’t work. The Yorktown-class had the ability to launch scout-bombers directly from the Hangar Deck via waist catapults below the flight deck. They eventually removed them.
