So Predator has been a guest character in MKX and Call of Duty: Ghost. As Alien and Predator been guest characters in other video games? Also would you like to see a Alien or Predator as a guest in another video game. If so which one?
I think Predator in SoulCalibur would be cool given how the Predator has a large selection of weapons to use and the Soul series is a weapon combat fighting franchise. Since the Predators have been hunting humans for centuries and the Soul series is set in the 16th-17th century, they could try to tie that in with the Predator's story.
