Wait a few more years and then apply as Captain to QR or the other UAE airline (if I'm not mistaken you're too young to apply as DEC right?). Why go back to being an FO when you don't have to. It's not a good career move, don't let the Dubai/Emirates glamour fool you. So many Wide body FOs at QR and the other big UAE airline are dying to get on the left seat on the 320 including many 380 pilots.
The excitement of the 380 will wear thin in about 1 year I promise you then you'll just be starring into space for years wishing that you were in the left seat. At the same time guys who would join the 320 in the left seat at QR or the other UAE airline at the same time you would be joining EK will have moved up to the wide bodies way before you would come up for command.
Seriously man don't move down to the right seat no matter what you're offered. If getting out of India is a priority then there are so many other choices. If you want to live in the UAE then you could even give Air Arabia a go and gain experience in the region before applying to one of the big three as DEC.
