The super short Ger/BB/1915 works pretty well

I have this inboard profile of what is probably the Ger/BB/1915 very short design study from the early 1970's. There is a minimal specification for the ship, and I have extrapolated the needed details, as well as taking advantage of the available slop in the design to add capability. The basic concept is for a 60,000 ton ship with 9-18in BLR and 24-5in QF guns, all in turrets. The ship has a tower foremast and a tripod mainmast, with large directors with long rangefinders. The main problem is the ridiculously deep draft, which would have been prohibitive, in practice. This is the Springsharp report:
