Yes, that's very possible but the MCs name is "Haranson", son of Haran, Lot. It's made very explicit that the story is basically just an imaginative version of Lot and his daughters. His daughters were literally the mothers of the Moabites and Ammonites. So the girls are themselves of this ethnicity ... basically, what I didn't even see myself until now, is that the writer is essentially announcing loudly and clearly that the characters are of Jordanian ancestry (or close to it, Lebanese, Syrian, etc.). This, together with many other subtle and not so subtle clues, suggests that they're not Indian strictly speaking, although the larger ancestry is Indo-Aryan or Indo-Iranian.
The writer mostly I think just wants to do something interesting and outside the norm, both with respect to the models and the story. He (or she) doesn't want to impose on the reader any particular interpretation nor on the characters any particular ethnicity. But I do think that there are enough clues left laying around that we can reach fairly safe broad conclusions about what they most likely are.
