We have trained many Indian students who have subsequently converted the FAA CPL H to a DGCAA licence.
It would be much simpler to do a CPL / CPL conversion rather than splitting training.
What we do is provide extensive supporting documents to our students that demonstrates satisfaction of DGCAA CPL H requirements and so far to date we have never had an issue with a conversion.
You can do your RT licence here in Florida (JAA) or after your return to India - it really isnt an issue.
I have many friends in India who are in senior flying positions that we have trained and may help you get work when you return with your shiny new licence.
I would also recommend a 44 conversion prior to returning as the 44 is becomming very popular in India for low cost commercial ops, a number of our recent graduates jumped into 44's on their return.
