An early redesign could turn Fisher's large light cruisers into useful carriers

What could Fisher's large light cruisers become if redesigned as carriers early in construction?

If converted before weapons and upper works were installed, they could become purpose-oriented carriers with space for about seventy-two aircraft.

The useful moment for conversion is early, after hull machinery is fixed but before armament and upper works lock in the original cruiser arrangement. At that point the ships can be planned around aviation rather than forced into a compromise later. The converted ship could carry roughly seventy-two aircraft under those assumptions. The result would use the large hulls for a coherent carrier mission instead of preserving features that made the historical ships difficult to employ.
