WI:Casimir III of Poland marries Bonne of Bohemia

Jutta(Bonne) was originally betrothed to Casimir III of Poland, however this arrangement was broken and Casimir married Aldona of Lithuania instead. After Aldona's death, Casimir was betrothed to Jutta's elder sister Margaret, however this betrothal was also broken and Casimir remarried to Adelaide of Hesse.

What if this marriage pushed through?

Bonne of Bohemia had many sons would she provide Casimir male heirs like what she did with Jean II of Valois in OTL if she married Casimir III instead?
 
A marriage with a Bohemian princess might change Casimir's policy concerning Silesia - most probably less fighting, more diplomatic manouvers and backstabbing. There is also a chance for Poland regaining with Bohemian help the New March (Neumark) and more successes in Pomerania. The rest will remain pretty much the same IMHO.
If Bonne gives Casimir a son and heir, that changes a lot in Polish policy. First of all, with succession secured Casimir's heir will not have to pay the Polish knights for support with privileges; central power in Poland in certainly stronger, which eventually might butterfly away "Nobles' democracy" in Poland; there will be no union with Lihuania - more an alliance against the Teutonic Order and Polish support for christianization of Lithuania (if it happens at all, but I think it will).
 
I think if Casimir III marries Bonne of Bohemia it also might mean that the Hundred Years War will be butterflied because Isabella of France was negotiating for the marriage of her daughter to Jean of Valois.
