What could six simpler Ryujo-class carriers have changed?

How might battles have changed if Japan had built six single-hangar Ryujo-class carriers with 24 fighters each?

They could have provided useful distributed fighter protection and made Japanese battle groups more viable.

Several simple carriers would offer a more viable force structure than concentrating twice as many aircraft in a compromised hull. Even a 24-aircraft carrier would add a useful flight deck to a battle group and could specialise in fighter protection. Several such ships would distribute aviation capacity while avoiding the reconstruction burden created by Ryujo's second hangar.
