Which European successor states emerge after an early peace?

Would Finland, Poland, Czechoslovakia, and the other postwar states still emerge if peace came in 1917?

Finland might still separate, but Poland and Czechoslovakia are less likely to appear in their historical form, Austria-Hungary may federate rather than disintegrate, and Russia could remain Menshevik rather than Soviet.

In this proposed peace, Britain chiefly wants German maritime power reduced, while France is more concerned with Germany on land. Russia's non-Bolshevik government also needs an outcome it can present as a victory. Finland is already moving toward separation and remains a possible independent state. Poland and Czechoslovakia are less likely to take their historical forms in this reconstruction. Austria-Hungary could become more federated, and the possible borders remain open to negotiation.
