SJ is a suit, but tall blue guy is also a suit

Hey, as we are all dying for more oxygen from Ridley, I thought I'd start another theory borne out of no evidence whatsoever... As I've suggested in a couple other threads, what if the SJ suit is such that you don't actually have to be of similar size to wear it. What if you can actually be any size - even a human - and put it on, and the suit itself will "grow" around the wearer to make a snug fit. As it is biomechanical, this should be pretty easy to explain. And the suit will make the necessary connection points to allow the wearer to operate the limbs and see through the eyes etc etc. Further to that, now I'm thinking well wait a minute, why couldn't the tall blue guy (I call Riddick) be just another suit!?! I mean, maybe the actual engineers have evolved into jellyfish/squid-like beings and don't have the dexterity anymore and therefore, they created these different suits for different activities. Again, this is just my mind making shit up while we starve, but please let me know your thoughts.
