Tillman's hypothetical maximum bomber carrier

What would a postwar Tillman maximum carrier, inspired by the Doolittle raid and required to operate bombers, look like?

Colossal, with USS United States treated as only the entry-level comparison.

The premise gives Tillman a postwar carrier project with no requirement to remain sensible. USS United States is the comparison offered for its scale, then dismissed as merely the entry-level version of what he would seek. The resulting carrier is imagined as colossal. No detailed dimensions, air group, or launch-and-recovery system are worked out.
