I like some of your ideas. I feel as a whole though it sounds to much like those light gun hunting games on the xbox. They are fun but i think the predator deserves better.
What if instead the predator your talking about is doing the above when a advanced unknown alien race comes to the planet for unknow reasons, for the time being, and they destroy the clan ship, with all or most predators on board. You only had bare minimum equipment, you already have used most of your consumables. Now you must stay alive, survive the deadly native creatures, including one that were off limits to you because of experience and equipment given to you, and now survive the advanced hostiles that destroyed your family and avenge them.
Additionally this could be a story that explains the creation of the Black Predators, the survivor is the progenitor / founder of the Black Predators we see in Predators and AvP:Evolution. The aliens that attached him were addicted to biological augmentation and manipulation. They would travel planet too planet, using what yhe salvaged of the black goo, from Prometheus which i feel IS ROYAL JELLY, they were adding the dna of dangerous creatures in the universe too their own.
Proclaiming that the old ways were dead, it injects itself with the black goo, becoming a new lifeform, a different type of predalien from my perspective. It had seen it clan members that survived the ship too ship battle die when they wouldn't have IF they hadn't honored the ways of the hunt against the new attackers.
It would rejoin its clan mothership, it would bring about a new law that would destroy the old, the ways of change.
Also additional you could have some fun hints that said attackers are the precursor too the thing, they haven't gathered enough attributes from other alien creatures and or shot them selves up with black goo to be as infectious as they are seen in the movies and games. They would have an alternate history to the ones in the John Carpenter universe just like how Blade Runner experiences an alternate history in the AvP Prometheus universe.
