Space Jockey seat 'back engineered' by the Engineers?

Was the Space Jockey seat design, used in Prometehus, 'back engineered' by the Engineers? One or two clues: [img]http://youheartsnark.files.wordpress.com/2012/06/alien-comparison.jpeg[/img] the scale of the Prometheus Engineer/Pilot is all wrong the Prometheus Pilot has 'alienised' skin the Elephants in stasis in the Prometheus pre-production sketches all suggest (to me) that the Space Jockey in Prometheus (with a Pilot getting in and driving it) is actual back-engineered Elephant Race (aka Alien space jockey) technology - - I'm assuming the Priest Clan Engineers are MAGPIES, seeding and borrowing from intergalactic sources where they see fit. :)
