SH4: FOV fix for better situational awareness

Magnification appears too low on the periscopes so I’m looking for a way to widen the view. Usually the AFOV was around 54°-57° on German periscopes, which is the width of a 27″ display at arms length. Any mods that make this happen? What is the AFOV of US periscopes?
