Following the conclusion of World War I and the post-war treaty the German Navy was permitted to retain three of their pre-dreadnought Deutschland class battleships. While Deutschland was scrapped in 1922, the Schleswig-Holstein and Schlesien served into World War II. Both were given extensive refits in the 1920s, but was there any consideration to skirting the rules of the treaty and doing a complete reconstruction? Since Germany was not allowed to build new battleships, could they have gotten around this by literally gutting the ships to the bare hulls, building hull extensions, and creating new ships in all but name only? Basically what I am think of is similar to what the Italian Navy did with the Giulio Cesare. Were there treaty limitations, financial limitations, or a combination of these and other factors?
