Six Alaska-class ships as carrier escorts

Could six Alaska-class large cruisers have been more useful than North Carolina- and South Dakota-class battleships outside World War II?

Potentially, because they could provide fast carrier escort and overwhelm heavy cruisers, though a Kongo-class opponent would remain a more demanding fight.

The Alaska class can stay with a fast carrier force and intercept surface threats that break through the outer screen. Its guns would make very short work of enemy heavy cruisers. A Kongo-class capital ship would be a harder opponent and might not be a fight Alaska should prolong. The design occupies a useful escort niche between ordinary cruisers and true battleships.
