I have a small event idea if mod developers are interested.
Was playing National Populist Russia with Wrangel as dictator. I was out of any alliance and captured Germany myself. IMO what here should happen is that Russia assumes leadership in Mitteleuropa alliance and gets decisions to redraw the map of Europe how it wishes with new block of National Populist dictatorships in Europe.
As Russian Empire it should be possible to overthrow existing monarchies and place own dynasty to the thrones of Austria, Germany, France and UK. However I haven't played as Russian Empire yet against Germany and I don't know - maybe such an event chain already exists.
