ELI5: With the Neanderthal genome sequenced, how can scientists bring one back into existence?

My understanding is that multiple full Neanderthal genomes have been sequenced.  I have wondered for a while whether or not it would be possible to bring one back into existence, possibly using a human as the surrogate mother and viruses to modify human eggs and sperm.  Has this been discussed before?  Is it possible in the near future? What is the likely scientific process that would be used?

Assuming that they could accurately reconstruct the DNA in physical form (possible, but expensive), they could do it.

Of course, then you come to the ethical dilemma of making a human woman carry a non-human fetus, and then if the child is born, raising a possibly human-intelligent non-human as the only one of their kind.

tl;dr it's doable now but it will never happen because of ethics.
