Timeline planning discussion: Casimir III survives to 1390's

Here is my idea

On 1370, Casimir III decided to be careful about his own life and not to engage himself of things that would be harmful to him like hunting after a bad dream about his own country.

In 1371 Vladislaus of Opole and Casimir III led an armed expedition against the Crown of Bohemia (this assault caused a terrible devastation of Moravia) which led to the treaty of Krakow of 1371 which had the Duchies of Cieszyn, Raciborz, Bytom and Opole to be under Polish Suzerainty as an exchange for peace.

On 1378, after Elisabeth of Pomerania was widowed from the death of Charles IV of Bohemia, she was recalled and she was married to Siemowit IV, an ally of Casimir III.

The Children of Charles IV would have some sibling rivalry and for that reason, Bohemia would be unstable, however they would be unstable and any war between them.

Wenceslaus IV would speak ill of the children of Elisabeth of Pomerania with Charles IV, in this point Siemowit IV would have children of his own with Elisabeth of Pomerania.

How would longer living Casimir III affect the Hussites in Bohemia, how would a longer surviving Casimir III affect the Hussite controversy in Bohemia if it still happens ITTL?
 
I don't think that he would be so successfull in one expedition to Silesia, especially if he had problems with expanding Lithuania (they would for sure try to at least disrupt building a castle in Vladimir as in OTL). Plus he would be wary of Teutonic Order.
But after the death of Charles of Luxemburg he would be more successfull in struggles for Silesian dukedoms. Still everything depends on the succession: would he sire legal son eventually or not?

About hussites: hard to say. If Venceslaus was unsuccessfull against Casimir it would be possible that the whole Hus' carreer is butterflied away. AFAIR it was Venceslaus who allowed the Wycliffe thoughts to be spread in Bochemia and supported Czechs in Prague University against other nations.

The expedition to Silesia was not that successful and for that reason it was only Upper Silesia that was gained, it was more of a support to Vladislaus of Opole that he accompanied him in the battle but he himself is not successful but he used his victory for his own gain.

Since ITTL Casimir III is living longer, he can assign a heir, a Piast relative is most likely.
