So, I decided to start an Austria campaing. So far, things were going good, I got a PU with Hungary and took all provinces I need from Venice. And now I have ~20 years left to deal with Papal State. The problem is their alliance with France. While it seems to me that this war is winnable, it'll probably take too long and I won't be able to start the 2nd war before The Shadow Kingdom event will fire, while annexing all the provinces I need in one go would probably lead to a huge coalition against me.
What's the best course of action in this situation? Is there a peaceful way to get The Papal State to join HRE?
