I feel as though the Iron Patriot will work fine without Osborn.
Crossing characters, like Whiplash and Crimson Dynamo is a bit of a different story.
Norman Osborn is the Iron Patriot. He might be called the Iron Patriot. It may look like his armor. But it won't be the Iron Patriot. It will be IPINO.
The Iron Patriot was an armor that the Green Goblin, Norman Osborn, wore to be a political pretty boy. Before he donned it, Stark was going to use it in memory of Captain America.
Iron Patriot is an armor, not a character.
