Extradiction would be unlikely for such crime(even cases of terrorism can take years for extradiction, or may not even take place). But it would be possible to get them arrested in India.
That said, there are literally millions of people in India who have graduated with whatever degree/certificate, can speak English, and are willing to work in any kind of scam, as long as they get money to buy food. You can setup a office in Noida/Mumbai/Pune/Bangalore etc, and hire these people for dime a dozen. Things getting risky? Close everything and start anew in another city.
Problem lies in poor law enforcement in India, and lack of awareness among old americans.
