We're looking at it as though there was some kind of united India. I don't think that was the case. The Indian sub-continent was a collection of disparate states.
I don't think we are. Well, I'm not. I'm quite aware that India at the time was not a unified state, which was part of the problem for the mutineers. But solving this (and their other) problems is basically what this thread is about!
Also, I wouldn't use the word 'depraved' to describe the Mughals. Screwed by the decades war war forced on them by the emperor Aurangzeb, certainly, which led to much of what was the Mughal Empire breaking away and taking its own path. Not to mention Aurangzeb's changing the politics of India from being based on tribal and geographic boundaries, as they were for centuries, to being based on peoples identification with and alignment to their religion. Also, I think you'll find that the Mughals were well-integrated with India as a whole, unified their realm, and could certainly be considered to have been better for their people than the British and other Europeans. However, we're getting off the point a bit here.
Another point is that the British forte was (and still is) administration. Their troops got paid regularly, the mutineers did not. As soon as the opportunities for loot ran out, large numbers of mutineers started to desert ( and indeed rejoin the British forces.)
Well, part of my question was and is, what if an Indian or Indians learn this from the British and can apply what they have learned on the side of the Mutiny? For example, as you say, the importance of paying ones troops?
I'm quite sure there were enough intelligent Indians around at the time for this to not be out of the question!
In a similar way to how I speculated on a leader being able to rally/unify the mutineers enough to make the British suppression of the Mutiny a longer and harder job.
