You could do something with the Armenians in
Cilicia though, currently I just put Armenian cores there, but if they ever actually gain independence that would give them control of almost all Eastern Anatolia from the Black Sea to the Med, which is perhaps too much. Also there's the problem of Armenian rebels perhaps not being able to liberate those areas, so you
could create a separate tag for the Cilicia Armenians. Just call the country Cilicia (or "Kilikia", that's what it is in Armenian, I think) and give it cores on Adana (894), Marash (896) and Antep (898). It would be basically a revival of the medieval
Armenian Kingdom of Cilicia.
