Despite Resurrection being kinda gash, I'd actually be pretty excited by the prospect of more Ripley 8. As a character, she could be very interesting, with the part-Alien vibe she's got going on. Let's be hoenst, that angle was never really explored all that thoroughly in the film, apart from finding the odd use for her acid blood and having her sense the Aliens occasionally (but completely sporadically).
With some more thought, it could be really cool to expand upon her inhuman traits. What's more, the +200 years timeframe could be fun to explore.
