@Jordan isle The Current Day Earth-6160 Ultimate Universe? Maybe it could work with a younger Tony Stark and that would be a way to bring back Tony Stark to the Main MCU but the 1610 Ultimate would simply not worked with the MCU right now. Those versions of the characters are too far different then the MCU or even the 6160 Counterparts and the Current Actors would never play them.
On the off chance this happens, I would not be surprised if the Knights were completely disconnected from the MCU High Evolutionary. Comics HE toyed a lot with the mystical and supernatural. MCU HE seemed very confined to the scientific and natural.
