Barbettes should be mountable on tower/hull barbettes

[nightraven1901]

As title.

The barbettes you include on towers and hulls should be able to mount barbettes on them to permit triple-superfiring designs and generally allow more customisable design work. At the very least, these positions should be able to mount barbettes their own size or smaller, or have selectable heights and girths (including "none."). The French super battleships being able to mount a barbette behind the hull barbette can be charitably deemed very silly. If these tower/hull barbettes didn't get in the way I would dislike them far less.

I see this as a necessary stepping stone on the road towards truly customisable designs.
