Maybe the title sounds a bit crazy, but I do explain:
Let's consider the most favorable scenario for a German victory in WWI: both France and Italy are military defeated, the US do not intervene, UK wants peace with Germany without many conditions, A-H collapses in many new entities which would depend on Germany for sure, Brest-Litovsk is at least partially implemented in the East etc etc.
After that, Germany has a lot of peripheral new entities ready for being puppetized. Instead of implementing those artificial projects of Mitteleuropa confederations and so, Willy might be tempted to recover the old title of Holy Roman-German Emperor and unite all these entities under the symbol of the Imperial crown.
Unlike the title of German Emperor, which is quite restricted to the German nation, the title of HRGE could bring legitimacy over dominions in Central/Eastern Europe which were either part or had strong ties with the historical HRE for centuries.
In fact, the reality would be the same as expected IOTL: a German core with lot of vassalized entities (Duchy of Poland, Kingdom of Hungary etc.), but with a diferent symbolic formula which could bring more historical legitimacy to this new entity.
