Well Babur had artillery, so it would be very very hard to beat him, but assuming they managed it, there are a couple of ways it could go down
Historically, when the Rajput confederacy fought Babur, it was to reinstate the Lodi dynasty of the Delhi Sultanate. If this happens, then there’s not really much northwards room for Mewar to expand without taking the capital of the Sultanate. There is also the situation where Rana Sanga claims the entirety of the sultanate for himself (although I’m pretty sure it would shatter the confederacy and the best case scenario for the immediate future is if he can consolidate the central and maybe the eastern part of the sultanate)
