A buddy of mine was a MCPO on the USS America (the last non-nuke carrier?) He said it was more dangerous duty than his days as a helicopter door gunner in RVN. Said he was happy to hear that damn thing sank with nobody aboard!
If we want to help India, give them a new one!
It depends on the condition of the ship upon decomm and how well it is rennovated for its new life. We have sold decomm ships to a lot of allies over the decades. That said, what would India do with a supercarrier? Outside of an LPH, that is pretty much all we would have to offer for carrier aviation at the moment.
