In truth Gene, I dont know!
I do see your point, but many Mararajah types certanly did fight from the front in battle & many had dozens of sons. {as well as wives & concubines.} Who needed to stand out from the crowd.
I think Indian Royal politics was very machevelion at the time, with intrigue,poisening & murder,bieng common. It was tough to get to the top.
I wouldnt be surprised if some sons prooved thier fitness by such deeds. Common? I doubt it, but thats all just conjecture I have no proof.
Interesting discusian though!
