*jumps up and down*
Thats ones for me!

Of course in my argumentation one has to consider that I wont strictly go by traditional borders, but also by other considerations
Areas to consider:
1) West Germany - Well, the thing with the former Prussian provinces of Rhineland and Westphalia is that you cant simply make own states out of them and be done with it. The border would go right through the Ruhr Area, and thats unacceptable, and then theres also the Palatinate which needs to be included (it could theoreticalyl remain with Bavaria, but exclaves suck). And if the two are one state, then that state would be way too large in territory and especially population. So, there needs to be a division, and needs to be south of the Rhine-Ruhr Area, with the southern partition gaining the Palatinate. In so far the borders actually make sense.
What Id change is of course primarily that Hesse keeps its traditional lands

- that is, Rhine Hesse (the Mainz-Worms-Bingen area), and the part sof Nassau lost to R-P IOTL. In return, R-P gains the Aachen region, so that *North Rhine Westphalias southern border is indeed just outside the Rhine-Ruhr Area. Maybe North Rhine and Westphalia could even be seperated (with the Westphalian parts of the Ruhr Area of course staying outside Westphalia)...
Oh, and the Saarland: No need for that to be an own state. To Rhineland-Palatinate.
2) South Germany: Baden and Württemberg both have large enough populations to remain own states. So they should stay seperated. Maybe Baden can also gain Ludwigshafen, its the only economically viable part of the Palatinate maybe, but this way the Rhine-Neckar area is together. And Ive always been for seperating Franconia from Bavaria. Maybe, as further Hessian expansion

, Aschaffenburg to Hesse - its way better connected to Frankfurt than to Würzburg anyways, and the borders of regional leagues always already include Aschaffenburg with Hesse, for example...
3)Harz/North Thuringia
The borders in the Harz are completly artifical and ahistorical! Especially Thuringia goes way too far north. I mean, it needs to absorb some parts of the former Prussian province of Saxony (Erfurt was part of that province, even!), but not that much. I think much of Northernmost Thuringia should hence be part of Saxony-Anhalt, and Lower Saxony "lost" some parts there that used to belong to Hannover and Brunswick, too.
4) Bremen
Do we really need an own city state for a meager 650k people or so? Either that goes to Lower Saxony, or alternatively my proposal of a State "German Hansa", encompassing Hamburg, Bremen, Lübeck, Cuxhaven and Bremerhaven

(That it would consist of 5 enclaves isnt that bad - theyd all be sea ports, after all)
5) General Note on OTL Eastern Germany
Current borders of the East German States are ALL ahistorical, and unlike the borders of the GDR states they suceed (before those were abolished and replaced by the GDR districts), because they largely still follow the borders of the GDR districts. Needless to say, Id give them the historical borders

Well, except of that one part of Mecklenburg sticking out, and the exclaves/enclaves at the Mecklenburg/Brandenburg border, those things can be corrected.
