AHC: 30 Years' War spells the end for the Holy Roman Empire

The challenge here is for the Holy Roman Empire to collapse as a result of the 30 Years' War. How might this happen? Could a bungled handling if the Bohemian Revolt by the Empire lead to a deadlocked electoral college? Could the Siege of Vienna have gone better for the protestant side? Could Sweden have avoided war with Poland, allowing them to intervene when the Danes did? Could the survival of Gustavus Adolphus in Lutzen have brought the Swedes to Munich, or even Vienna?
 
The obvious problem I see is replacing it. We're talking about a war in which the sides were more or less evenly matched. In our timeline, it took an attempt by one country to puppetize the Continent to abolish the HRE in our timeline, and even that was not wholly allowed to die given the German Confederation established to succeed it (and the wartime Confederation of the Rhine), and the consolidation of nation-states which followed.
 
I do have a few, namely revolving around the idea of the drawing of camps in a far more volatile way in the lead-up.

Is it possible that with a PoD at the Peace of Augsburg, the debate over cuius regio, eius religio is simply not settled in a satisfactory manner? I mean, yes, I can't say that the doctrine was exactly satisfying to anyone at the time, but at least it was agreed upon and ratified into the treaty. Could things degenerate so badly at this point that, while much of the rest of the treaty remains in forec, this facet in particular is never satisfactorily settled?

Without Protestant legitimacy and an, essentially, live-and-let-live policy in both camps for the next 60-70 years, could it be possible that, despite peace, when the THirty Years War breaks out that, instead of trying to maintain the HOly Roman Empire, which arguably with cuius regio, eius relgio was a practical and political body, be seen instead as a corrupt, Catholic institution by the Protestant forces where, even if the 30 Years War ends as OTL, that is with stalemate and Westphalia, it is decided that the Protestant states withdraw from the Empire...thus weakening it significantly, and perhaps create their own Protestant Union or something of that effect under the guiding forces of England and Sweden financing this counter-weight?

Mind you, this doesn't truly dissolve the HRE, but does split it up and, I imagine, create a mortal wound that also sets a precedent that permits states to leave the Empire on their own volition. One by one, the territories secede from the Empire and soon the HRE is just a fancy name for the Habsburg domains and their satellite vassals too weak, indebted, or afraid to break away.

Not sure how plausible this might be, but it seems to be the only practical path if you ask me.
