Winning the 30 years war should make all members of the winning religion in the HRE like each other

When the league wars are won by one side, they don't actually gain any opinion boosts with one another in celebration of their victory. Winning such an event should build solidarity between members of that religion in the HRE, making them very unlikely to attack one another for some time afterwards. I'd suggest a boost of +50 with -1 decay per year between all members of that religion in the HRE, unless they sided with the other religious league.

Co-league members should definitely get a relationship boost before, during, and for some period after the war as well, I agree. I don't think it should be based on religion, though, just league membership. If you're helping the protestant league, protestant league members should like you more even if you're catholic.

This doesn't account for the possibility that the new emperor doesn't actually participate in the war, which is why I said members of that religion within the HRE. That said, a general opinion boost for all members of the same league would make sense too.
