Reaching is really an understatement. But we can all play at this game if we adopt that kind of warped logic.
I suggest that all these clues lead to Jessica Jones. Here's why: Galactus is on those covers. He wears mostly purple, as does Thanos. Who else wears purple? The Purple Man. The Purple Man controlled Tony Stark in that A:EMH episode "Emperor Stark" and he'll probably show up at the end of IM3. Purple Man also controlled Jessica Jones when she was first a superhero.
That hand symbol in the first clue wasn't a diamond pointing to Vision. Rather, a diamond is a precious jewel, and Jessica's superhero name was Jewel. As Jewel, she also fought the Avengers under the control of the Purple Man, but was defeated by them. Later on, Jean Grey, who also appears on those comic covers, gave Jessica a psychic link to prevent her being controlled by him again.
Jessica Jones also ties into Spider-Man. She was born Jessica Campbell, and was at the same high school when Peter Parker was bitten by the spider. She also had a crush on Johnny Storm - tying further into the Fantastic Four. She was later in a car accident with her parents and they collided with a military convoy - hence the military motif in the 2nd clue. She ended up in a coma but the rest of her family were killed. When she finally awoke, it was because of the first coming of Galactus and the Silver Surfer.
So all these previous clues and the comic covers tie into Jessica. Marvel were also planning a TV series AKA Jessica Jones before they began working on SHIELD.
But maybe I'm reaching here.
