Baby Nom

[Black Widow]

Yes it is possible if you consider the /\lien movies, tradionally human hosts became impregnated with an alien embryo via an incubi (facehugger). But in Alien 4 they cloned Ripley in a bid to try an get an intact queen alien. during the cloning process ripleys dna was merged with that of the queen alien she had in her. So she was made as a hybrid and had their powers even their acid blood.

So it is not inconcievable to have a nomad human hybrid, most probably feasible through genetic engineering than copulation though
