They would never go the route of the Iron Patriot because the suit alone is basically Iron Man with a red, white, and blue motif. A move like that to an audience not familiar with that stage of Norman Osborn would instantly link that persona to Iron Man and possibly percieve it as Evil Iron Man. The Thunderbolts version of Green Goblin would be the better route to take as far as his appearance, like I stated earlier, they can use the Ultimate Goblin as a hallucination that Norman sees in his mind, especially given the fact that Goblins were a fear that he had when he was a child, so his costume is modelled after something that scared the hell out of him. Ultimate Goblin being Osborn's main appearance would make him almost similar to the Lizard, thus giving audience yet another "transformed" villain. I don't think people would want to see 2 films with both villains having similar origins.
