I'm not sure about modern India. You can only have 10 modern countries, and I think in Asia we'll see at the very most 3, counting the Soviet Union as European. Besides India, there's PRC, South Korea, Japan, Vietnam, Thailand, Bhutan, Indonesia, Iran, UAE, Israel and Turkey as viable options, so I think, for me personally, there are more interesting choices than a fourth India. Yet, the leaked maps, sadly, seem to indicate modern India (not 100% sure on this interpretation).
Mughals would be nice.
And not really India, but united Nepal or even Medieval Malla would make a nice addition as well - probably not in Vanilla though.
