The Ger/DL/1915 alternate version

An alternative version of a German destroyer leader for 1915 was 390ft long and had a beam of 40ft. I had thought that giving up one 5in mount and adding a twin 23.6in TT mount would be beneficial. With that, the design could achieve a 36 knot speed. The "look" is very German, although of a later era. There is long forecastle and two funnels with prominent caps. This the Springsharp report:
