Charles pulling a Kingdom Title out of his ass might be a bit much, but what if he Revived a title? There was the Kingdom of Arles/Arelat, which ties to the Burgundy of old and when Rudolph III of Arles died without issue the Kingdom passed to then current Holy Roman Emperor Conrad III over the next two hundred year the Kingdom title popped in and of existence, Some Emperors skipped it, others took up the title or changed the name to King of Burgundy, the Back to being King of Arles. After Lothair III the Emperor's stopped bothering to use it.
Now Separating out the Burgundian Inheritance and placing it under an new/old Kingdom title, would piss off a lot of the princes, but it could be see as a way to separate the Netherlands from Spanish Control, at this Point in History Charles is the only one who could really do it without a war taking place.
As is the Netherlands had fallen into a gray area. They were part of the empire but they where ruled over by a (technical) vassal of France. when they slowly came under the rule of the Dukes of Burgundy. After Charles V the Netherlands would still be in that gray area of being ruled by a foreign power, this time Spain.
Now the person most likely to be pissed off is Charle's Son Phillip, he would want that dutch piggy bank all to himself. But if the Netherlands were ruled by their own local king, your more likely to see a conflict between the ruling heads of the family. something along the lines of "Why should I give you loans, that you will never payback, so you can go to war with the people I do business with?" Also a Habsburg King of the Netherlands might actually make the jump to Protestantism.
Which is kinda why the Dutch revolted against Spanish rule to begin with. Also it could cause the break up of the Empire once the Thirty Years war happened. You could even see an anti-Emperor elected in opposition to Ferdinand II and Ferdinand III. A Winter King that lasts longer than Frederick V did.
Is it possible for the main line of House of Habsburg to continue so that Habsburg Lorraine does not come into the main territories?
Charles VI had a son (Leopold John) that only lived nearly seven months. Make this child live to adulthood and have male heirs and the House of Habsburg remains.
Except Charles IV named the King of France was the perpetual vicar of the Kingdom of Burgundy, so Charles V can't "revive" the title because it was de jure part of France.
Would Old Fritz attack anyways?
