Turning the fictional Karge battlecarrier into a usable warship

How would the US Navy use the fictional Karge battlecarrier?

Convert it into a conventional fast battleship by removing the flight deck and rebuilding the central superstructure around its existing heavy battery.

The panel treats the World War design as evidence that a navy has already lost control of its requirements. American service would likely begin with a long dockyard period rather than immediate deployment. One proposal removes the flight deck and substitutes a conventional battleship superstructure while retaining the machinery, armor, magazines, and main battery. Because much of the valuable hull remains, the conversion is extensive but not equivalent to building a completely new ship. The conversion shows how a failed hybrid can still contain a viable conventional combatant.
