I would like to suggest you to break Germany and Italy for the bigger map. Have 2-4 civs like how it is on RFC Europe but of course less extreme because the bigger map will still have a smaller Europe that RFC Europe has. I could suggest have things like Saxony, Prussia and Bavaria for Germany and Venice, Sardinia and the Papal States for Italy. Maaayybe Naples but Naples was more of a Kingdom controlled by outsiders (HRE and Aragon). Then, when the 19th century kicks in, we have Germany and Italy form in their correct times, based on the development of the civs. How about it?
