I heard that Jogaila was born before 1350 if this is true is it possible for his Brother in Law Casimir IV of Pomerania to arrange Jogaila to marry Elisabeth of Pomerania in order to strengthen Casimir IV's claim as the heir of Casimir III and to get an ally, one of the things that will come in this marriage is a possible earlier union of Kreva, if a Polish-Lithuanian union is made due to Jogaila marrying Elisabeth of Pomerania due to Casimir IV dying heirless like in OTL how will it be different from the Polish-Lithuanian union of OTL.
