As for me, revolutionary states should be more reasonable. If revolution happens in an italian state, like Tuscany, it should become Rev. Italy instead of Rev. Tuscany. It would recieve some event giving it casus belli on all states with provinces in Italy region. That would make more sense, because revolutionarees would rather intend to forge a state basing on a nation, not artificaly forged feudal country. Same for Germany. If revolution would hit some german state, it should strive to unite Germany. And Ottomans should become Turkey, as mentioned.
