My 'gut' objection to the endeavour is that they're creating a new "genetically modified" creature without any consideration for the ecosystem which surrounded the originals. Not just the plants and animals that made up the Arctic ecosystem 10k years ago, and now, but - more importantly - the ecosystem (parasites, gut biota, etc) that used to live on/in those mammoths. The gut flora in particular will be critical if they want these Indian-elephant born mammoths to thrive in the Arctic - will the creatures even be able to digest what they eat? If we have to revive something elephant-related, then I'd much prefer them to concentrate on (one of) the Madagascan elephant bird species. The eggs alone would offer a potentially robust revenue stream for whichever God bought the beast back from the dead.
