I'd really honestly rather Rebecca Jorden/Newt, Dwayne Hicks and Ellen Ripley all stay in the graveyard, but if you've got to do it, you've got one chance to make it worthwhile. Do it professionally with the people who deserve to, all the first three Alien films created parts of the franchise so iconic, parts of them exist in everything the franchise releases now. Personally one of the reasons I think to get it right an alternate sequel requires James Cameron or David Fincher, or both, anything else just feels wrong.
