As newbie i have also one suggestion
I would suggest to separate the Holy Roman Empire and Germany, each with its own UP, UHV's etc. Similar to ancient Rome and modern Italy.
Seen in another modmod.
The Holy Roman Empire (starting year 800) with the aim of the control of Italy, the Balkans and the German countryside, to produce a certain number of great personalities and never lose a city to France, Russia, Vikings and Germany until 1815. Or to establish Protestantism and to build his holy shrine.
UP: The Power of Emperor> always invited to the conference and his vote counts twice
Germany (starting in 1740) with the new task until 1915 three cities in East / South-West Africa and two cities in Oceania (excluding Australia and New Zealand) to found. Besides the goal of conquering parts of Europe.
