Hmm, can try going for an independent Hungary. They wold run as a sorts of eternal regency without a king. Albeit as a constitutional monarchy they would be very close to being a republic. Thr language reform is in full swing but it also resultes in unexpected tensions with Hungary's other nationalities. Meanwhile Austria would wish to reintegrate Hungary and the Russians are also eyeing them. This is thr basic premise in mind, we'll see if I can put this into writing. EDIT:Or a Venice which sided with Napoleon. Reforms were introduced, the Doge was exiled and a new (actually democratic) republic was formed. After Napoleon's defeat Venice paid a huge sum and had to give away three quarters of their fleet to the victors.The Doge took back his office but the republic didn't return to the status quo. I don't know which I am going to write yet. It'll be a few days before I'm going to have the free time anyways.
