I once saw an alt-historical map (perhaps on deviantart.com) on which the Polish-German border was on Pilica to the west, and has continued along the Bug River. Had been presented there an alternative medieval stage on OTL Polish lands.
I'm interested in the development of Poland with such borders. In this assumption Poland would be absorbed by Lithuania or would be grew a Weichselmark soon ?
