Firstly, Coulson would make a great Vision. He's calm, patient, hardly shows any emotions, yet seems kind and caring. Just the way the Vision should be. So I am all for that. Plus, it would let him come back with more style than just "oh, he's not really dead, we lied to you".

Secondly, hardly anything is comicbook accurate in the movies.

Thirdly, to have a comicbook accurate vision you need Ultron and Wonder Man, to have a comic book accurate Ultron you need Ant-Man. So, since none of these is present so far, you could have a comicbook accurate Vision in Avengers 5, maybe 4, but not in Avengers 2.
