My apologies, I don't mean to come off that way, genuinely.
I just don't see any real difference between something like this and the original film. In either situation, be they Comanche warriors or Dutch's team, the Predator could kill all of them in a matter of minutes if it chose to just sit in the trees, cloaked, and fire its plasma cannon at them one by one. That's just kind of baked into these movies. Dutch and his guys' weapons were all essentially ineffective, as they couldn't land a shot to save their lives, and the Predators like toying with their prey which inevitably leads to their downfall as the hero character taps into their inner primal nature, rather than their technology, and uses that to come out on top.
To me, this seems like a neat concept to just scrap the superfluous "modern" technology right from the start. And because the human characters here will be starting from a slightly lesser playing field weapons wise, that will likely ramp the tension up more.
