There is SF/ASB alternate history novel
Lód ("Ice") written by Polish SF writer Jacek Dukaj portraying world, where ww1 never happened and Russian Poland still exist in 1924. Although POD for this story is ASB event-different Tunguska Event (impactor brings to Earth mysterious material with unusual physical properties called 'tungetyt' and Ice creatures called 'lute') which created new branches of industry based in Siberia, making Russia great again

Abstracting from ASB element, political development of Poland does not seems that unlikely. Author even stated in epilogue, that in his opinion such outcome looked much more logical than crazyiness of OTL. Dukaj wanted to debunk some Polish national myths, for example myth of Pole as eternal conspirator obsessed about independence. In Dukaj's novel prominent Poles are interesting in making fortunes in Siberia and do not bother about such "nonsense" as independence. Piłsudski is Japan-backed terrorist, active in Russian Far East and is generally regarded as dangerous troublemaker, even by Poles.
