Some Byzantine (Eastern Roman) buildings

I remember eons ago someone asked Sandy Petersen why did the Byzantines used the Middel Eastern build set and he basically said 'because they were in the Middle East'. Tell me, do these building look middle eastern?

So, what do you think? Should Byzantines (how I hate that name) get another buildset, from the existing ones? Making another one would be a pain in the onager for the developers, I guess.
