Yes there are some small groups in OBC reservation at state level including some ST groups for Christians. But the numbers are very small and the lion's share of the benefits are taken by Hindu groups. Some states like Kerala, TN e.t.c. have a specific Muslim OBC group and that allows them to use that reservation fully. And although it has helped muslim in the south to climb up the social ladder. I don't think that this is the best way to provide inclusive growth.
