Designing a more useful 1928 Panzerschiff

How practical would an all-forward, 30-knot Panzerschiff be if Germany designed it in 1928?

It could be useful, but a smaller, faster-firing battery may fit its cruiser and commerce-protection roles better than six 11-inch guns.

A more useful 1928 Panzerschiff might use 9.2-inch guns, with even 6-inch guns considered, or an 11-inch forward battery backed by 6-inch weapons aft. The suggested roles are fighting in the Baltic and protecting Germany's South Atlantic whaling interests. The existing 11-inch guns are judged too slow-firing for encounters with several cruisers yet insufficient to make the ship a true capital-ship opponent. An all-forward 11-inch arrangement could be supplemented by several triple 6-inch turrets aft. Germany's gun industry limits the alternatives: scaling an existing 11-inch design down to 9.2 inches is considered more practical than developing a larger weapon, though the resulting gun could be heavy.
