I think if you paint them the right colors and add a few details here and there - and maybe take a few away here and there - they'll work just fine. Remember that before 1948 India (which included the modern Pakistan and Bangladesh) had very substantial population of Moslems and those models fit with their architecture. But, really, I think the way you paint them will make the biggest difference since they could work for all of North Africa, most of the Middle East, India, and a few of them for the American Southwest - but I'd paint each location a bit different. And I can't say how to paint them for you because I don't know what part of India you are focusing on (not that I'd know anyway but the research is fairly easy on the internet, I'm sure)
By the way, if you find other and better options, I'd love to hear about them.
