The division of Germany was agreed upon at Yalta OTL before anybody made it into Germany. If I had to guess, if the WAllies caused the Germans to collapse in the west sooner there'd be a similar conference in which occupation zones would be agreed upon earlier. The Soviets are bound to get a slice.
I suppose the Soviet slice could be limited though. The Allies could agree to Germany's eastern border being on the Oder and the Soviets would enact their revenge upon the German population east of the Oder. There'd probably be a portion of Berlin that they occupy too, although I'm guessing that if Berlin is jointly occupied the Soviets wouldn't let their men do as they please - there'd be too many outside observers.
If there's no Soviet occupied Germany, that creates a different issue though: The prospect of a unified Germany right after the war. West Germany and its rearmament was controversial enough OTL, and West Germany wasn't a polity bigger and potentially stronger than France. The urge to break up Germany in the west might be stronger. Alternatively, there might be more western willingness to have Germany lose territory in the west. Part of the reason that none of the Bakker-Schut Plan Proposals were accepted was because Germany already had 14 million refugees from the east. There'd still be expulsions from Poland, Czechoslovakia, Hungary, Romania, Yugoslavia, etc but if the border is on the Elbe that probably means some 5.5 million fewer expelled Germans.
I think the maximum territories desired under the Bakker-Schutt Plan are unlikely. The Dutch PM Wim Schermerhorn wasn't all that into the idea of annexing German territory, but Queen Wilhelmina was. Per wiki...
In 1946, in the name of the Dutch government, he officially claimed 4,980 km2 (1,920 sq mi) of German territory, which was not even half of the area envisioned by Van Kleffens. The Dutch-German border would be drawn from
Vaals via
Winterswijk to the
Ems River, so that 550,000 Germans would live inside the Dutch national borders.
550,000 Germans annexed to a country of 9 million doesn't seem that unworkable - there might not even need to be that many people expelled.
In 1947 there was another proposal put forward by the Dutch Government.
At a conference of foreign ministers of the western allied occupation forces in London (14 January until 25 February 1947), the Dutch government (Cabinet Beel I) claimed an area of 1,840 km2 (710 sq mi). This claim included, apart from the island of
Borkum, large parts of the Emsland, Bentheim, the cities of
Ahaus,
Rees,
Kleve,
Erkelenz,
Geilenkirchen, and
Heinsberg; and the areas around these cities.
In 1946, about 160,000 people lived in this area, of whom more than 90% spoke German. This plan was a very simplified version of the C-variation of the Bakker-Schut Plan. The
KVP considered this proposal much too small, while the
CPN rejected any kind of reparations in the form of territorial expansion.
The drafters of the Bakker-Schutt plan seemed open to the idea of letting Germans be naturalized as Dutch if they (1) had no family members up to the second degree in the rest of Germany, (2) had made efforts for the Dutch during the war, or (3) spoke Low Saxon instead of High German.
The annexation of Southern Schleswig back to Denmark could occur too.
The Belgians had
their own annexation goals that by 1949 they gave up. Interestingly, they were pretty minor (mostly amounting to absorption of some municipalities just across the border) and the Belgians didn't plan on expelling anybody, though they did expect (at least provisionally) the people there to retain German citizenship (so no voting in Belgium, I suppose). There were (and still are) German exclaves surrounded by Belgian territory. There was a railroad the Vennbahn that goes through Belgium and Germany, and the railroad itself was (and I think is) considered Belgian territory. There were some other small municipalities and forested areas just over the border that they wanted too.
Luxembourg's demands started with wanting back the Luxembourgish lands lost in 1815 at Vienna, plus expansion of the border to the Saar River. Most Luxembourgers thought this was a bit much though. Eventually they lowered the demands to all or part of the German districts of Bitburg, Our, Saarburg, and Prum (31,188 people) - 20% of the lands lost to Prussia.
France might be able to directly annex Saarland and keep Kehl.
Heligoland could to Denmark or back to Britain.
As for chopping up Germany, Adenaur was a Rhenish nationalist at one point IIRC. The idea of dividing into a North and South German state also was proposed (Roosevelt Plan, Churchill Plan, Adenaur Plan, etc). Division into a Rhenish West German state, a SwaboBavarian South German state, and Prusso-Saxon East German state could perhaps have some sticking power.
Three-way division, with France, Netherlands, Luxembourg, Belgium, Denmark, and UK getting a piece.
Ruhr is under international administration.
