I was hoping to play a Nation that consists of the Ottoman lands west of Istanbul? Walachia, Serbia, Yugoslavia, Crimea and the such.Your first idea is likely impossible with a Polish-Hungarian union and Khazaria around.
Or possibly a North Italian Nation consisting of Sardinia-Piedmont, Lucca, Parma, Tuscany and Modena, maybe even incorporate the Swiss.
Hmm.. not sure but it's for sure either of those.
Especially since half the countries you mention didn't exist and/or were part of the above mentioned two nations.
The second idea can work albeit I don't even have the faintest idea how the hell the Swiss are coming into the picture.
They're literally at the other end of Europe.
Well if you would care to take a look at the map that I put above, Sardinia-Piedmont consists of Genoa and Savoy, Switzerland is directly north of Savoy.
