Custom weapon calibers?

[Spitfire109]

So we all want custom hulls eventually. I think that's a given. But id like to be able to personally set the inch or millimeter to a certain type as opposed to all the common types. This isnt too big a deal on the large main guns on battleships, but is more noticeable on  smaller ships. For example German cruisers preferred 150mm guns, while Russians preferred 130mm. We have 152 and 127 mm currently but there is a difference especially if you're trying to make replicas. While on the subject of guns, I do want to see little things like AA or machine guns added. Even if no aircraft are added, they still see use against torpedo boats and small destroyers, and just make the boat look cool. As well as quad barreled guns, cause those where actually rather common leading up too WW2.

A way to implement this would be to keep the models of the closest caliber while creating a best-fit approximation model of performance values to get in-game stats.
