What's sort of timeline gymnastics would be required to create an independent Pomerania that includes both Danzig and Stettin?
The Samborides ruled Pomerelia (Pomerania-Danzig) as an independent duchy until the dynasty's extinction in 1294. Maybe if the dynasty survives longer (and Poland remains divided enough so it can't forcibly devour them), it could eventually intermarry with and inherit the Griffins (or vice versa).
Assuming a state like this can be created and sustained, how wealthy could it get, holding the mouths of both Oder and Vistula?
