Sj suite an incubator for sjs?

Sorry if this has been discussed elsewhere...but just came up as a thought: What if the sj bio-mechanical suit is but an incubator for the-to be sjs? We see an sj's dead body and possibly the crew examining his detached head...then taken to the lab for experiments...then found a creature in the helmet...a pink fleshy squid.... What if what is in the urns is being placed by the sjs into empty sjs suits and sealed by the helmet. And the suit acts as an incubator for the thingy in the urns..And as it grows up becomes the squid...if then left uninterrupted it would use the sj suite as a giant cocoon and evolve into a fully grown blue guy who fits the suit perfectly... What if one of these squids was interrupted violently by the crew of Prometheus..that would explain its agility and aggressiveness against the crew...and how fast and instinctively attacks with swift precision, because it is protecting the life of the-to be sj ...and is fully aware of its environment...and since it is that effective it was chosen or made by the sjs the vessel or preserving their life and help it evolve.... Ok..any thoughts?
