He most definitely won't have the time, but Shahid Khan def has the aura and the presence to be the badasss babyface owner/promoter who shows up once in a while to make sure things don't get out of hand too much, like Bil Watts in Mid-South or even Gorilla Monsoon in the 90s in WWF. He would serve the role far better than any on-screen version of Tony. I cannot imagine Shahid Khan ever in his life stating that he feared for his life because of another person. This is most definitely projection, but as I said, watching him reminded me of the many badass desi uncles I know, who look like him and also have that aura.
Hey, in fact, his schedule might mean he only shows up like 5 times a year at most, which really is the most number you want to see an authority figure on screen.
