Alien lifecycle

I've posted this in the ''Fly In The Soup'' thread but I thought I would put it on a seperate thread too. I'm wondering if Ridley Scott is going back to the original Alien film concepts and story, as has been speculated. Remember in the Alien 'special' edition there is the cut scene reinstated where Ripley comes across Dallas cocooned and also what looks like Brett sticking out the top of an egg. I'm guessing that originally the Alien could start some kind of reaction that would transform people into eggs/facehuggers. Brett would have been turned into the egg/facehugger and Dallas would have been the host for the resulting facehugger. The eggs in the cave in the original could be the transformed crew of the derelict. All the crew were changed to the egg state waiting for someone to come to the planet and be infected, then possibly leaving for other planets on whatever spaceship had come to the planet. This would account for no Queen Alien as Scott has stated that the Queen was not his original idea for the Alien lifecycle.
