American battlecruisers as cruiser-killers

If Canada ordered battlecruisers, what American battlecruisers might the United States build in response?

Likely 14-inch Lexington-style battlecruisers built for scouting and cruiser-killing, with enough hulls to maintain forces on both coasts.

American battlecruisers would serve as scouting-force assets rather than line battleships. Four to six ships could provide availability on both coasts, with 14-inch guns and a design light enough to hunt cruisers rather than resist their own armament. The proposed programme also shows how doctrine, congressional appetite, and gun layout influence one another.
