A cruiser design for emergency mass production

Which cruiser should Britain and the United States mass-produce in an emergency?

An Edinburgh-subclass Town cruiser, with five-inch/38s replacing the four-inch battery and additional anti-aircraft guns.

The choice is the Edinburgh subclass of the Town class, represented by Belfast and Edinburgh. Alex would replace the four-inch secondary battery with American five-inch/38 guns. Additional anti-aircraft armament could also be fitted.
