Okay I can agree with the point that you made. How about relocating the Poles and germans in the area with land being swapped between the two ethnic groups. The Poles would thus gain most of the land, no germans would be in Poland and the Germans would continue to have the land connection to East Prussia. While no one might be 100% happy with it I am sure that the Poles and Germans could live with it without it being a cause for future war between the two.
About White Russia and the Ukraine I think that you are missing a Key point historicly the Poles have a great attachment to both areas. They ruled the Ukraine at one point and probably would like to either control it or have it in hands that might be friendly to Poland. The Polish military also wanted Poland to have far more resources and a greater buffer zone with its eastern neighbor.
