If, after the Congress of Vienna Prussia and Russia had gotten their way about Poland and Saxony (and much else besides, but that's irrelevant here) and Russia had got Posen, Prussia only keeping West Prussia, is it plausible and in period that the Tsar and the King of Prussia could have set up an exchange of their Polish and German minorities, West Prussian and Silesian Poles for Posen and Lodz Germans, to lessen their mutual minorities problem ? Let assume that ITTL Congress of Vienna Prussia got Bohemia-Moravia plus a lot of other stuff , so it's going to have a sizable Slav minority nonetheless.
