Here's an idea - the Russian provisional government bows out of the war rather than wage the Kerensky offensive and only loses Vistula land, Lithuania, Courland, and the Kresy. When the American join the war, the Russians reenter but the French are insistent that there be an independent Poland with the border from Russia's peace with Germany kept intact.
Russia gets Wilsonian Armenia as compensation for lost lands. When the Turkish Nationalists start a fight, Greece and Russia beat the Turks down and Greece makes big Anatolian gains. The Greco-Turkish population exchanges then occur.
Meanwhile Russia backs a Greco-Serbian partition of Albania. Greece deports the Albanians to Turkey since the OTL population exchanges were based on religion not language or ethnicity.
Britain's OTL attempts at pressuring Italy into ceding the Dodecanese succeed as well here. Later on when Cyprus becomes independent Enosis goes through because the Turks are too weak to stop it.
