Your Attila looks good, but I agree with the Wolf. I've always thought of them as barbarians rather than an actual civilization.
I'd use him as Tamerlane of the Mongols, though... (Tamerlane was Turkic, but not Ottoman)
Ekmek, you remember versatility from when you made that Cesar Vallejo leaderhead, but mentioned he could work as Santa Anna. Civ Gold uses him as Bernando O'Higgins of Chile.
There is already a Tamerlane LH made by Iloveplayciv, but it was only released on the russians forums.
