To be fair the Alaska class was meant to murder the hell out of the IJN's heavy cruiser fleet which due to Far Eastern Fleet's actions is far smaller than otl at this point. Of course if Guam isn't that far along making effectively a larger Albany/Chicago out of her is completely viable since the only reason why Hawaii wasn't converted was the fact that she was almost completed and thus a conversion would take a lot of work and hence money. If the USN does do this however lets hope they add a second rudder to her.
