I would love to see Will Smith play Mike Harrigan's son in a Pred film. Or if that didn't work Idris Elba as Mike Harrigan. I know he was in Prometheus but Bill Paxton was in both Aliens and Predator 2. He's got that frame to take on Pred. I think Titus Welliver is a great actor and you could cast him as a lead. I also think that guy out of the Kingdom show Frank Grillo, real bad ass but imposing actor.
