Hi Adeel,
I would say keep the cord blood. I don't know if this is done yet in India but you should contact the BMT center and ask about cord blood transplants there, but a newer approach to CBT uses a less harsh chemo preparation. The result is a mixed chimerism where both the original and donor cells co-exist, without rejection. Only about a 20% engraftment is needed to produce a hemoglobin level of 10. This is a fairly new approach, so its use is not yet widespread, but if available, my opinion is this is preferable to a BMT. You should talk to the doctors at the BMT center and see if they can use the cord blood for a transplant, before you make any decision.
