Would it be acceptable to incorporate Ahura Mazda, Angra Mainyu, and the other deities of Zoroasterianism as a "stand in" for the God of the three big monotheistic religions in Planescape? Since many people are touchy about incorporating Him into D&D, I'm been looking for a good substitute.
Officialy, the religion is monotheistic, with the other gods looked on basically as angels or evil spirits. However in actual practice, the other good deities allied with Ahura Mazda are invoked and do have spheres of influence (i.e. divine portfolios). Or is this too close to the other monotheistic religions to be acceptable?
Ahura Mazda and company in Planescape?
