The challenge is to have a 3rd major German state, besides Prussia and Austria, with a POD before 1870.
Some ideas:
Bavaria
A more federated German Confederation?

Bavaria would work. A more German majority pre-Napoleon POD Swiss state might be possible. With the right manipulations, the Netherlands could fill the role. Hannover as an extension of the United Kingdom could be possible, though that one is less likely.
Historically, the Wittelsbach (Prussia) and Habsburg (Austria) rivalry also extended to a third family, the Luxemburgs. If they keep Bohemia and maybe Hungary they could have some clout, or if they inherit into a few of the smaller states in the Rhineland and low countries they might be respectable.
In the time frame Lascupa0788 seems to refer to (the 14th and early 15th centuries), the Wittelsbachs and Luxembourgs intermittently ruled the Margraviate Brandenburg. The Hohenzollerns became the ruling family in Brandenburg in 1415.You mean Hohenzollern. The Wittelbachs are Bavaria
