Some of those images are almost exactly what I was toying with when I mentioned setting AvP in a distinct universe that was isolated.
I have this idea i've been extrapolating for a few weeks now, where an Elder Predator (ala Predator 2) basically decides he's getting up there in age and grabs an Alien egg. Basically going on his last hunt, and he's going off to this really hostile alien world in deep space.
The humans in the story are a group of mercenaries/bounty hunters, and they're going to set down on the same planet and do some kind of an exchange/deal outside of the watchful eye of Colonial/Planetary Authorities. When they show up and make the trek to the rendezvous they find their associates are all slaughtered or missing. They explore their ship, and discover signs of the hunt in progress.
The human characters are then stalked over the course of the day and night by the Predator and Alien. Who engage in several melees with each other.
At some point some of the survivors are chased back to their associates ship and take refuge within, as they are trying to hide and avoid the Predator/Alien they discover a nest in the bowels of the ship where some of that crew are egg morphed/morphing.
The final engagement would have the few human characters scuttling their associates ship, and trying to lure the alien and predator inside. Who will survive? Haven't decided yet.
