Not true. Many of the Ottoman's core provinces are not actually state culture. I'll elaborate:
Non-state culture:
Romanian: Wallachia, Moldavia, Dobrudia, Bujak
Magyar: Magyar, Maros, Pest, Banat, Transylvania
Ruthenian: Ruthenia
Slovak: Carpathia
Albanian: Albania
Georgian: Georgia
Kurdish: Kurdistan, Nuyssaybin
Armenian: Armenia
Syrian: Aleppo
17 non-state culture core provinces in historical territories
State culture:
Turkish: Antolia, Thrace, Kastamon, Angora, Konya, Antalya, Taurus, Adana, Sivas, Daghestan
Arabic: Syria, Lebanon, Samaria, Judea, Sinai, Egypt, Alexandia, Delta, Cataract, Nile, Quattara
Greek: Macedonia, Hellas, Morea, Ionia, Crete, Corfu, Cyprus, Rhodes
Slavonic: Bulgaria, Rumelia, Serbia, Bosnia, Croatia, Ragusa, Dalmatia
36 state culture core provinces in historical territories
That is a third of the OE's historically conquered provinces that are not state culture. There is already a 30% penalty to monthly income from non-state culture penalty. Tying the census taxes to culture places far too much emphasis on state culture. All so that certain german and italian minors can more easily benefit from a lot of ahistorical expansion?
Culture is already very powerful. If a german minor -- or heaven forbid, Austria -- were to take control of all of Germany, he could benefit from 100% monthly income due to culture and with 10 centralization he could get 100% census as well. War exhaustion would be problematic but not unmanageable, due to the lack of culture based revolt risk (no +2 rr due to culture difference). Religious differences would be manageable due to conversions being dependant on (again) culture. Monthly income, conversions, and revolt risk are all directly tied to culture already. Making another major economic factor dependant on state culture would be overkill.
You also argue that core provinces are arbitrary and the current rules unfairly favor nations with a large number of cores. Well, it is oft discussed how the state cultures are assigned somewhat arbitrarily; far too many nations have multiple cultures, according to some. Your suggestion would just favor nations that have the big cash cow cultures (german, french, arabic), rather than the superpowers. At least making census taxes dependant on provincial claims doesn't further screw the historically multi-cultural, multi-denominational nations even more.
It is just a matter of opinion now, SJG, but your idea just doesn't wash.
