It's going to be hard to frame Von Kluge as a communist/democrat/whatever...at the very least Germany would lack a proper scapegoat for Hitler 2.0 to blame.
Never underestimate the blatant lies and outright imperviousness to facts that makes conspiracy theories work. After all a superficial look at 1918 would make it extremely impossible to see the leap from "Commie Jews killed Germany" to the armistice in October that the first iteration had. The second one would probably claim that von Kluge was a snooty aristocrat who didn't see how actually close to the outright annihilation of the Slavs WWII was in 1942, and if he'd only not betrayed Hitler and the Nazi cause that cause was surely going to relieve Stalingrad, the psychological effects of which lead to Soviet collapse.
We're talking ATL conspiracy theories. What grounding in facts do they ever have? There doesn't have to be one, just enough plausibility to make it somewhat swallowable to the right kind of person.
