The Union Navy utilises a lot of what are "United States Ships" in that other universe. With most of those it will be just copy/paste unless there is something I think that could have been done better at the time. I understand the need for the halt on instituting new weaponry designs so that those in production could be mass produced as retooling is what takes the time. The one event I would like to change for that is to upgrade the 5"/38cal singles and twins to the 54cal model before fixing production or even replace them with either the UK 4.5" (in my twin turret model-see CUS Columbia for details) or 5.25" which the CUA Navy would have access to through its Canadian Commonwealth connections. That connection could give some interesting combinations for the smaller ships.
The CUA Navy policy is survivability for its battlefleet and so never built battlecruisers only battleships. Even its early scout cruiser force was made up of armoured cruisers rather than the true scout/light cruiser used by other navies as the eyes of the fleet. It was not till 1923 that the CUA started receiving a class of 'light' cruisers that were half as big again as any of the British or German equivalents.
