I could see it turning out okay. The ones under control of the West get the carrot and the ones in the Soviet sphere get the de-Nazification stick, as OTL. Prussia, despite continuing to exist, gets its much-deserved deflating. Eventual reunification into a Bundesrepublik possible (or, if we're being fanciful, some kind of latter-day HRE constitutional monarchy, though naturally much less likely). Unification, if it happens not as fast as die Wende.
Added bonus: Austria will find it more difficult to ignore its past because there is no "Germany" for them to pretend they were victims of. Also makes Grossdeutschland more likely, which is nice for people like me that still hold grudges against Hitler for, among many many other things, poisoning that idea.
I don't like how these states swallow up Thuringia, Baden, Schleswig-Holstein, etc. etc. Perhaps these Roosevelt Germanies can federate themselves to restore some of the history.
The main thing that makes this unlikely is opposition from Stalin, who won't want a Prussia this big. Perhaps an iron curtain farther east makes it possible.
Also, that ain't German, it's Dutch.
