In my opinion, most of the Indian F/O's will fill up those leftseat spots once their ready for it, It happens evrywhere, if you have the time and the skills, & the airline is in need, they will switch seats with you in the blink of an eye.
Im going as a Captain and im looking forward to it very very much!
& the experience its even more exciting with startup airlines, in wich your are part of the thing since the beggining, to this I can relate a lot.
good luck
see you in India
