I think a TV Series based around Hicks and Newt and loosely around the Aliens novels by Steve and S.D. Perry would be ideal. I'm sure that, even if this project fell through, Biehn and Sigourney would be all about doing one in the future - of course, due to her age, Ripley would only play a cameo role in the series. But, a Series with Hicks and Newt as the male and female leads respectively with a dark/horror bent to it that preserved the mystery and Lovecraftian beastliness of the Alien would be most ideal.
