I note that Jet Airways has a partnership (not codeshare) with Air France - if you're able to redeem your miles for a ticket on Jet Airways, why not elect to transfer somewhere in the Gulf, and so land directly in COK as your first point in India? This will also mean that (a) the transit timing is a bit earlier in the day and (b) if you pick Abu Dhabi or Kuwait, then at least you have some comfort on the degree of convenience that you'll have during transit.
