None of the Reichskommisariat are surviving under any circumstance barring German victory. Even if they win in the East and lose in the West (like WWI), then if they didn't just turn the Reichskommisariat(s) over to the Soviets, then they'd set up an anti-communist Russian (or Ukrainian?) government in the territory of the Reichskommisariat. Which would basically be an act of war against the Soviet Union, and the Soviet Union would want to resolve that situation as soon as they were able to, meaning World War III. You'd have to have way more anticommunist leadership than OTL in Britain and the US to get that done.
