I was leaning somewhat in that direction, something of a hybrid Arabic/Renaissance Medeteranian for my area. With some more rustic rough-and-tumble folks in the mountains, leftovers of a vast but forgotten ancient (elven? dwarven? x?)empire, that leave well enough alone and are content with their hidden cities carved into the living rock. These peoples would be more like the early Ottomans if they had never advanced past the middle ages and having lost a good part of the 'civilized' part of their civilization, with the newcomers having inherited much of their leftover culture and twisted it to suit them. The lands very nearest the mountains would be occasionally raided by these remnant tribes, but local (well armed) militias and fear of military reprisals would mostly keep them at bay.
