Having Judaism be so widespread is ASB. If you want another unifying religion, use some Roman-based religion or something. I can't comment on anything else's plausibility, because the Hindu/Buddhist divide would depend on what nations are where. It seems plausible with a 2000 year old POD for those two religions to have spread.
