Reformation Without Hapsburg Spain

How might the Reformation unfold, if Spain was ruled by Miguel de Aviz and the Holy Roman Empire was ruled by a longer living Philip the Handsome? With the Holy Roman Empire not as distracted with Italian concerns, might a Catholic Emperor defeat the Reformation? Or perhaps without Spain as part of the Hapsburg Realm, the Emperor might convert to Lutheranism? Or maybe something entirely else, please give your thoughts.

I can´t see the Emperor go Lutheran, the whole reason the princes did was to weaken the power of the Emperor over them.
 
Well, Henry VIII gets his annulment and England retains its Catholic theologian-King, which would definitely have huge butterflies for Protestantism's survival as a geopolitical entity.
 
I really don't know much about Philip, but he seems to be an opportunistic asshole from the little I read about him, maybe he could try to use him for some benefit (he wouldn't convert though).

Also, wasn't the Netherlands (Philip's personal domains) home to many humanists like Erasmus? Maybe he could get influenced or something and be less extremist like his OTL son.

Yet quite a few of his subjects did. Styria became largely Protestant, as iirc did several other provinces, while Bohemia had a large "Hussite" element even before the 16C. They weren't reconverted until the Counter-Reformation. It's entirely possible that the ruling family might have done likewise had they not been Kings of Spain as well.
