Is this any more ridiculous than the (everlastingly stable) long line of German puppets all the way into Persia, a Japanese Siberia, a "Cossack State" centered just about anywhere, and the permanently detachable Ukraine in its 1960s borders? I don't think so. But we both have our biases, so it's all good.
I do agree with the autocratic state bit. It makes sense, because the only territorial successes it had was under autocratic governments with a populist appeal. You can thank the neighbourhood for that. However, you make it sound like there's something innate about this condition, rather than simply a function of the survival of the strongest alternative amongst many others.
It's not ridiculous for the things in your first paragraph to be established in a WWI-ish scenario, but it would be ridiculous for them to remain in that form, even if the CP win. All those things did happen to some extent. Do you think an independent Ukraine is impossible after WWI? I don't think it's reasonable to argue that. It wouldn't have exactly the same borders, ala the Recurrent Kazakhstan Problem, but it's pretty possible given a few chances from OTL. The Baltic States, Poland, and Finland managed to persevere, so the only unrealistic ideas are Japanese Siberia, a Cossack state, and any independent Belarus, which would require the entire populations of Poland and Lithuania to commit suicide and everyone in Russia to forget it's there.
But these are not as ridiculous as Greece gaining Eastern Anatolia and Istanbul. The population of Greece was 5M, half of which was in the northern area captured only in 1913, most of which was occupied by the CP during the war, and which had a minority Greek population. W. Anatolia and E. Thrace had a population several times that, and the Greeks would have to supply by sea and fight extremely seasoned veteran troops and officers on their home turf.
At least in CP-victorious TLs puppet states carved out of Russia had the support of an adjacent Germany and A-H.
