@Silver Fox What would also be pretty sweet is if Ellis figures out exactly how to reverse-engineer his suit. It was built using research from Geth and Reaper study, so it would almost certainly be fully compatible. Phalanx could become Taevon 2, in a sense. Barring that, it would also be pretty cool if the program Phalanx could be integrated for potential commandeering of Ellis' suit, henceforth known as the Cerberus Leviathan Mk-1, allowing the pair of them in a single body to have the Cyberwarfare and tactical processing of a Geth, with the unpredictability of a human. Phalanx would most likely also have control over Ellis' limbs and visual systems, allowing Ellis to fire from his right hand, and Phalanx to aim and fire with his left.
EDIT: In fact, the main problem would just be the Cerberus VI, NERO.
