My answer to the GB/BB/1914: the Ger/BB/1916
I would have built these in numbers to contest the North Sea and Channel against what the British were building. This is the original concept, with 9-18in BLR and 24-5in QF guns. It has the thick armor, as in the original, but higher speed. I wanted a good mix of stability, hull strength, and seakeeping ability, and this is what resulted (from my 1971 notes):
