" it is obvious that blomkamp loves the alien much more than ridley scott. Can someone be rational and let blomkamp do the work he likes?"
In no way do I mean to be critical or insulting, but love for something does not equate to the ability to deliver a quality product. N.B. could be the biggest Alien fan on earth, but that doesn't mean he's got what it takes to make a good Alien film, or that his ideas will be any good. The Ripley inclusion is the big eye roller for me.
It's just my opinion, but it's really a hard sell bringing back Weaver and crew. The movies were made, and Ripley, Hicks, and Newt died. They were good solid characters, but they were human beings. Stuff happened, they died. Bringing them back would feel like some sort of novelty. Gibson's Alien 3 is always there if anyone wants to know what happened if they all survived. But really, there's a nearly unlimited supply of new characters that could be created.
Think of it this way, "a new direction, in an actual Alien movie". No deviation by creating some prequel series that is all over the road, not some continuation of the previous alien films with the same old characters, but a brand new Alien movie with new characters. Novels and comics are written all the time that have nothing to do with Ripley, and nobody freaks out. I'm old enough to remember Alien 3 being considered the end of Ripley's character. The cloning thing was weird enough, but retconning entire films just to include dead characters adds restrictions on the kind of film that can be made. I'd rather any new "true" Alien film have as much creative room as possible.
But should it happen, dollars will get you doughnuts it would be throwback city. Newt would wind up saying the "mostly at night" line, and probably run across some orphaned girl who'd she'd protect, and probably sing "you are my lucky star" to. Thus becoming the new Ripley. It would just be too cheesy. Gads, can we not and say we didn't?
