I'd imagine there's a skit to make ironising the whole situation, but I'm not sure anyone can pull it off just like him, or at all. Not this random guy refurbishing his older material to make a fake guest appearance. Before all his punchlines were days of hard work, and it would be twice of that to correctly mimick his style, gestures, sense of humor and guess what he'd say now. It'd be lovely to see a talented impersonator to try that, and using AI like that is just selling this guy cheap. He deserves a better homage if there's one needed, and not pushed like that for promotion and without contacting his family.
