Should we try to bring back ice age creatures?

A little while ago, the Dire wolf was supposedly resurrected but this is misleading. The animals created didn't have the same genome as a dire wolf; they are grey wolves with some genes from the dire wolf inserted into their genome.

It was once thought it would be easy to reconstruct the whole dire wolf genome using that of the grey wolf as a reference. However, once we actually sequenced dire wolf DNA it was found that they were as closely related to grey wolves as we are to chimpanzees.

But this raises an interesting question: which ice age animals would be the easiest to bring back? Many have discussed mammoths but the most straightforward would be the cave lion. This is because we have found mummified cubs in Siberian permafrost which we could get good DNA from and it's very closely related to the modern lion meaning it would be easy to reconstruct the cave lion's genome using the modern lion as a reference. Once we've done that we could use the reconstructed cave lion genome to bring back the even more closely related American lion (that is if any of you back in the states are keen on having lions the size of brown bears running around).

I ran this idea by some of my buddies back in the states and one who was half Native American said that 11,000 years on, his people still tell horror stories of ice age predators.
