The Mughal Emperor Akbar in an attempt to create one unifying faith for his empire established the faith of Din-I-Ilahi(Literally the Religion of God. Akbar would have been definitely better of letting somebody else choose the name), using elements from Hinduism, Islam and Zoroastrianism along with aspects from Jainism, Christianity and Buddhism. Din-I-Ilahi while promoted by Akbar wasn't actively enforced by him, and so never really spread outside of his immediate inner circle. His son Jahangir whose religious ideology was pretty hard to pin down(I.E he hung out with a Hindu Astetic one week, and demolished images of Hindu Gods the next) doesn't seem to have taken much of an interest in it, and it sort of just faded away over time.
Lets say that the religion survives, Akbar is more successful at propagating his new religion and it manages to survive as a notable force after his death, his successor is over all more amenable to it(Instead of Jahangir perhaps he's succeeded instead by his favourite grandson Khusrau?), and its established as the Mughal State religion. How does this change religious dynamics in the Mughal Court? Is it likely to spread down to the rest of the population? What are the reactions of the rest of the Islamic World to the fact that the second largest Muslim State just converted to another religion?
