I think Ottokar would succesfully conquer Austria and be the ruler of the HRE.
I notice that is considered a lot. Whatwould the Premisyl HRE be like?
What if the Hapsburgs dynasty was simply non-existent?
What would happen to Spain, Austria, the Netherlands and the HRE? What if?
In Spain, the Catholic Kings were pursuing a very aggressive marriage policy. Without the Hapsburgs, they still would have tried marrying with the HRE current ruler, but chances are it would not have been as successful. Without a shot to the Empire, the sure-fire card was Portugal.
A personal union with Portugal would have been attempted in a more airtight way, maybe marrying Juana with Joao II's bastard, Jorge, and supporting the efforts to legitimize Jorge (which were unsuccessful IOTL). In this manner the 3 Kingdoms would have been joined without the Portuguese successional crisis that rose the Braganza to throne claimant family.
Spain as Portugal + Castille + Aragon, with complete dominion on oceans and a very strong position in the Mediterranean, and without the headaches of the true black hole of keeping the supply line around France to isolate it and to hold the United Provinces (in fact, without the Hapsbugs, Spain needed not to be mortal enemy of France)... it's a formidable thought.

The House of Luxembourg and House of Wittelsbach become even more prominent and remain so longer, possibly to the present day.
