As somekind of reminiscence of the earlier days of the Ottoman Empire it would have been possible for the Ottoman Administration to set its focus on some common sense. The Ottoman Empire saw itself as an successor state of the Byzantine(Roman) Empire which is more or less very true.
The founding dynasty got its connection to the old Byzanz by an important marriage between the Ottoman dynasty and the imperial byzantine dynasty of the Komnenos family and additional the just copied most of the byzantine administration and they even incorporated most of the byzantine culture so that it was possible for the earlier Ottoman period to evolve in some better shape than most christian kingdoms. But at the same time many byzantine cultural inventions were incorporated by the most important Italian Republics in those days after the fall of Constantinople. So we can tell that the Renaissance Era was just a consequence of the immigration of many byzantine christian intellectuals which help to change the cultural level of Western Europe in the following centuries and prepared many inventions which were in many cases only the copy of some byzantine ones...
In the later 17th century the Ottoman Empire got some change based on an islamic revival of a more conservative way which leads especially in the Arab peninsula to the ultra conservative islamic sect of the Wahabits.
The Islamic revival of the Ottomans would have been possibly lead to the more national tendencies of the Greek and not only the French Revolution and his consequences.
Until the late 17th century many officials in the Ottoman administration were of greek descendance and even christian. There were some more christian groups inside the Ottoman Empire like the Bulgars, the Serbs, the Armenians and perhaps half of the Albanian population and the Valachs the later Romanians.
For a very long time the Ottoman Empire was able to subdue the many mostly christian ethnies in a nearly modern approach by somekind of integration which diminished in the late 18th century by more foreign influencies like the French, the British and Russian ones.
As these nations appeared more and more in the eastern mediterranean area with many different interests they tried to get some parts of the Ottoman Empire for their own, especially the Russians in case of the orthodox christians on the balcans and in the caucasus area...
Thus it would be yet interesting for me as a little historian buff to see if there would be another approach to enable the Ottomans to survive long enough with most of its provinces against most of the odds.
There would be two different approaches possible:
first and above all the Islamic Way...connected with some modernization a faithful islamic Ottoman Elite could try to convert as much christians as possible to the Islam by strong taxation measures, by limiting most of the rights of the christians and by improving the cultural and economic situation of most Muslims - either Turks or Arabs and such else.
But on connection with a true islamic approach the Ottomans would need a modern army and navy combined with some islamic militias and a good strong Imperial Guard for the behalf of the Sultan.
Additional you as a player would need soe good alliances...
Either trying to to be an ally to the British and with the Prussian and perhaps with the Italians or in some other terms an alliance with France and Italy and perhaps even Persia, but the most successful would be the Britain - Prussia - Netherlands - USA alliance for some modernization.
In terms of a modernization and as a good help against Russian interest the last called alliance would be the best.
At behalf of the true islamic way it would be helpful to stay somehow neutral between France and Prussia and to be in a defensive alliance with Britain, France, Italy and Prussia to prevent the Austro-Russian influences on the balcans. Additional it would help somehow to modernize the Ottoman forces and perhaps the ottoman economics...
The more modern way would be a somehow dangerous one regarding the islamic majority of the Ottoman population. But if a good player would be able to install somekind of Parlamentiarian Monarchy like the Prussian model the Ottoman Empire would have been possible to survive even the Great War as the First WW was once called...
So I hope it would be possible that we could either get some additional event and such else data via the next patches if not already implemented or some explaination how we could do it for ourselves.
Or it would be possible to get access to some more factions via a later great update patch so we could eventually choose from about 12 nations I would suggest sofar...
