It would be interesting though if India converts to shia Islam and it's implications for Sunni shia divide in modern times as shia Islam would be the largest sect of Islam and we may see a union of Iran and India In the future
Plus if we see Hinduism surviving we may see Hindus becoming like Jews engaging in trade and banking with significant financial influence through the Asia and after contacts with European countries may be even in new world and these Hindus may outright support the colonialism in India by financing it
These are the things that comes to my mind
