With a POD before or during World War II, keep the German states mostly aligned with the Weimar internal borders. Bonus points if the Oder-Neisse line is created like in OTL, yet with:
* No separation of the Rhineland into two different states. with one attached to Westphalia and the other to the Palatinate.
* Baden and Wurttemberg are not merged.
* The Free State of Prussia can be allowed to dissolve, but only into its 1866 provincial borders (sans lands east of the Oder if need be).
