Poland gets partitioned between Galicia-Volhynia and Bohemia in 14th Century

I remember the Dukes of Galicia-Volhynia wanted to get the Duchy of Krakow, what if the Duke of Galicia-Volhynia, Yuri and John of Bohemia made a deal to Partition Poland, John of Bohemia gets Greater Poland, Teutons get Kuyavia while Yuri gets Krakow and Sandomierz what would happen to Poland if such a deal happens?
