What if Byzantium has the option to get Turkish culture after destroying the Ottomans? I agree on the Turkish lands hurting Byzantium's tech and such too much for the early game, especially since you have to take down the Ottos to survive.
I don't think that would solve this problem. Turkish as an alien culture and Sunni religion of many provinces results in a big reduction of tax income. Add to this the increased cost of gaining stability, the need to use resources to convert provinces and the events that give stability hits to the Byzantines and you have a nation that will no chance to stay anywhere near the western powers in the tech race.
Please do keep in mind that I'm playing the Mymap version, which means the Ottomans have a lot more provinces and it will take much longer to annihilate them, while the impact of the different culture/religion is bigger. But this problem will be the same for the new AGCEEP map, if that will ever come out.
Don't get me wrong, I think a Byzantine Renovation should be a big uphill struggle. I feel a Byzantine Empire that miraculously survived and prospered under a line of exceptionally strong emperors should have a much more difficult time than the Ottomans Empire did to become a great power. And not just for gameplay Byzantines = player only) or historical reasons (it didn't happen), but also because the Byzantines were just a lot more exacting towards their subjects and much less religiously tolerant.
Now back to my main point why the Byzantines should have Turkish culture at the start of the Grand Campaign.
From what I know about Asia Minor the region has been a ethnic-cultural-religious hodge podge up to modern times. While Sunni Islam may have become the dominant religion in this region and Turkish the lingua franca I believe there remained enough "Greek" people to allow the Byzantines to govern the region.
Also modern Greek and Turkish culture have a lot in common (discounting language and religion). I hope I'm not being naive in assuming that this would have been the same in the EU2 time frame, centuries before the advent of nation states and nationalism.
