I was just spitballing ideas so I hadn’t really fleshed out anything. My intention was more a replacement for royal houses so it would probably cannibalize some of their features.
I can think of a few features that might work for an Imperial Prince / Prince Elector site.
When the Catholics failed at killing all the Lutherans they came to a compromise where the secular rulers dictated the faith of their lands. It could maybe be a tech that gives healing units a watered down “Unction” ability like I described in my post about reworking royal house abilities.
- Imperial Election instead of Trade Monopoly
Could function similarly just with different theming. The candidates for emperor also handed out a ton of bribes to electors so that could be another tech to tie in with it.
- Imperial Diet
Not sure what the function would be, but it was part of their powers. Regensburg was where it was in session for the longest so maybe this could be unique to a Bavarian elector.
