It is very a pity. I thought that someone has made something similar. Interiors to alter difficultly and long, but I would be happy simply to do some shooting from main calibre. In SH2 I made changes in model of the ship and description of a submarine, and could do some shooting from ONE gun. In Destroyer Command it was absolutely simple. Poorly that DC2 do not plan to let out.
P.S. I hope you understand MY english
