Just so people know, there WAS a Space Jocky Alien hybrid in one of the comics. I actually have the full splash page of it scanned on my computer at home. I'll see if I can't put it up online somewhere for everyone to see. It's definitely kind of strange looking, with a ridge that runs from its "nose", down over the mouth, and connects back at the chin. It isn't solid, so it comes apart when it opened its mouth, but it did look kind of funky. In the comics, it showed up briefly bursting through a wall, covered in aliens as it rampaged through everything. The aliens attacking it, it crushing aliens while trying to go after the humans ship taking off.
