Theory - Terminator in the Alien/Predator Universe

This is all just foreshadow and theory mixed with a lot of wishes.

THIS POST DOES CONTAIN SPOILERS ON PROMEATHEUS If we go off of where Terminator Salvation ended, we’ll see how this can be set in the Alien/Predator universe. We start after John Connor and the resistance wins the war against Skynet and humanity rebuilds itself to beyond their former glory. The Weyland Corporation has by this time assumed control over Skynet and made it their own by advancing the A.I. technology made originally by Skynet. The year is now 2094 and Weyland Corporation’s CEO, Peter Weyland, died on the expedition crew that was aboard Prometheus. At the end of Promeatheus, it shows Dr. Shaw leaving the planet to go to the home world of the Engineers to get answers. Queue Promeatheus 2, or to be called “Paradise” according to this post http://www.prometheusforum.net/discussion/2028/scott-on-prometheus-sequel-and-title, goes to the Engineers home world only to find out that the Engineers and Predators are at war with each other. In a turn of events, that you should feel free to expound upon here, ends up with the Engineers going back to Earth to harvest human life to create a weapon to use against the Predators. While on the foot note of that ending, the Predators go to Earth to fight the Engineers and to stop them from making any new creatures/weapons from the Human race that would present an immediate threat to them. They go back in efforts to wage war upon the Engineers and/or eradicate the Human population to stop them, little do they know, Weyland Corporations has been spawning an army ever since they assumed control over Skynet thus defending Earth with artificial war bots. The Predators realize that Humanity is more than capable of handling themselves, so they side with them thus spawning a triple cross-over of famous series for an epic battle of proportions. TL;DR – Predators vs. Engineers (and Aliens) vs. Humans
