Even if it's for a brief scene, I would love to see Ed Harris return as Rear Admiral Cain AKA Hammer in Top Gun 3 with a more positive demeanour towards Mav.
Rear Admiral Cain/Hammer has to be in his 70s at least by the time of the third film and would very likely be retired - still, it would be nice to see him appear and give Mav acknowledgement to which Mav responds with a "thank you, sir" or something.
It was good to see Cyclone showing his approval for Mav towards the end of Top Gun: Maverick, I now want to see Hammer doing the same.
