Not at all. The Marathas were very much Hinduist, but they never forcibly converted Muslims as the geopolitical realities of the large Muslim minorities throughout India forced them to cooperate with them - in fact, there was even a
Muslim Maratha prince, and Hyderabad, the centre of South Indian Islam, was a vassal of the Marathas at one point. Hell, even the (very much Muslim) Mughals were vassals of the Marathas at one point. Very little conversion from Islam to Hinduism occurred, and Hinduism doesn't even have any conversion rituals.
Now, to answer the question. This is very, very difficult. Despite there being more than a few Turks who came into India and destroyed ashrams and temples, conversion never got past one-third of the subcontinent. What happened to the Turks is that they realized that forcible conversion was difficult and caused problems with their rule, so they dropped conversion, only retaining the jizya tax as a method to fill up their coffers. You need an empire in India that does not realize this, and continue to preserve conversion. The Ghurid Empire, very much an Islamic one, ruled both India and Persia at its peak. Presumably, if you keep them from collapsing, and also place its capital in Persia and only in Persia, you can keep them from realizing the problems conversion brings up. Maybe, if they are able to suppress internal revolts while still pursuing conversion, you can see a Muslim-majority India. But it's far from ensured.
