Absolutely not. No airline will accept a photocopy of an ID since it'd be trivial to counterfeit one. And these days just about every airline wants to know who flies with them for two reasons: a) avoid people with some evil intent b) allow identifying victims of a crash.
Air India on the topic:
For domestic travel within India, valid photo identification, namely, a passport, Income Tax PAN Card, Voterβs ID or Driving license is mandatory.
A copy is not valid.
