Your challenge, with a POD after August 1, 1914, is for Kaiser Wilhelm II to end up executed like how "Hanging the Kaiser" was a popular slogan in the Entente countries. It doesn't matter whether his execution is carried out by domestic revolutionaries (perhaps a more radical 1918 Revolution leads to Germany going Communist under the Spartacus League, who proceed to give the Kaiser the same fate as his Russian cousin)) or by the Entente, though there are bonus points if you could find a way for the Entente to do it as opposed to domestic revolutionaries.
