Re comments that the Occupation Zones would be unchanged -- weren't said zones not even finalized until Yalta?
The final scheme of four zones (including a French Zone) was finally agreed at Yalta, but the planning had been in progress for some time before that. I think the notion of dividing Germany into occupation zones to be administered by the "big three" powers had been raised at Tehran in Nov-Dec 1943, as well as the idea of revising Poland's western borders at Germany's expense. The European Advisory Commission that defined the occupation zones started work at the beginning of 1944, and had come up with a plan featuring three zones (Soviet, British and US) by May of that year. It wasn't signed off until the London Protocol issued in September, after the POD in this case, and was revised again at Yalta, but as far as I'm aware the basic plan was in place before Valkyrie went down.
Now, I allow that before anything had been formally agreed there might be a possibility of differing circumstances on the ground leading to further revisions and differences compared to OTL, but I think the facts are that the WAllies had already agreed in principle to the Soviets occupying Eastern Germany (and to Poland receiving a slice of German territory to make up for the territory it was losing in the East to the Soviets). I'm not sure this would really be affected by a faster German collapse or a different final line of contact between the WAllies and Red Army compared to OTL, because I think it's pretty clear that the WAllies would not allow any German government to avoid surrendering unconditionally to all of the Allies. And nor were they, apart from a few dissenting voices, eager to "betray" the Soviets as they saw it at the time by cutting them out of any surrender.
Obviously, from our position of hindsight, post Cold War and aware of the oppression the Soviet Union visited upon the countries unlucky enough to fall under its influence post 1945, it seems like something the WAllies might have, or should have, been willing to do, but at the time it wasn't so obvious. As they saw it at the time the enemy to be defeated at all costs was Germany, not just the Nazis but Germany the state and the whole notion of German nationalism and militarism, and all other concerns were secondary.
