I believe the Ottomans need some events conserning Crimea.
event = {
id = 123456789
trigger ={
exists = CRI
}
random = no
country = TUR
name = "Our Crimean Brothers"
desc = "The Crimean Khanate joined the Ottoman Empire in
1475. The Crimean Tatars are closely related to the
Turks of Turkey. They were loyal vassals of the
Empire for 300 years. The Ottomans ruled directly
only in the ports along the southern Crimean coast. "
style = 2
date = { day = 1 month = january year = 1470 }
deathdate = { day = 31 month = december year = 1477 }
action_a ={
name = "Accept the Crimean Khanate as our vassal"
command = { type = vassal which = CRI }
command = { type = stability value = 2 }

command = { type = addcore which = 464 } #Kaffa
command = { type = addcore which = 465 } #Kerch

command = { type = provinceculture which = 466 value = turkish } #Azow

command = { type = revolt which = 464}
command = { type = revolt which = 465}

command = { type = revolt which = 463}
}
action_c ={

command = { type = stability value = 1 }
}
I decided to change the cultures of Azow and Crimea to Turkish since Turks and the Crimeas were pretty close ethnically. The alternative is that the Ottomans gain the Mongol culture.
I still don't believe that Genoa still had land in Crimea after Tamerlane personally leveled their forts at Kaffa, but regardless there needs to be some event where Kaffa and Kerch go to Crimea. Perhaps some increased revolt risk for Genoa, but then there is a great chance that the lands will go to Georgia instead of Crimea which wasn't likely as Georgia didn't border Kerch, and was intensely divided at the time. The best solution would be an event where Genoa scedes the two provinces to a country of their choice upon the fall of the Byzantium to the Turks. Possible choices would be: (these are all just ideas) Crimea, Ottoman Empire, Poland-Lithuania, or Venice.
