I wonder if some of the earlier German dreadnoughts might be uparmed with 17in guns

I was pleasantly surprised that the German Koenig class battleships could be re-armed with 8-17in guns, at least by using Springsharp. I am reasonably sure that the Bayern class could be armed with 6 or 8 17in guns, at least if the ships were bulged. The question is if the Kaiser class, if not the Helgoland class might be armed with 17in guns. I am sure that 16.5in guns would be easier, but I am interested in the 17in gun. I may experiment tonight, with Springsharp, to see what I can do. This page has German battleship specifications.
