After the Partition of Poland, the only remaining Polish semi-independent state that is not small or insignificant is Teschen/Cieszyn - although it is a vassal of Austria, is it possible for the Duke of Teschen to acquire Krakow which was a condominium between Austria, Prussia and Russia then pull a Piedmont on Poland, gaining Galicia first then getting Congress Poland and Prussian Poland(Posen and Upper Silesia).
Is it possible?
