Bossy, Vezina, Potvin, Dryden, Hasek, Kane, Malkin, Matthews, Bedard (why is he listed?) Jagr, Lindros (though he likely would've been) Lidstrom.
Richard, Howe, Orr, Gretzky, Lemieux, Crosby, Ovechkin, McDavid. That's about it. I don't think there's a goalie who's been generational although Dryden and Hasek could make good cases for it. If I were to add any players it would be Doug Harvey (who likely would've won 9 Norris trophies if it existed) and maybe Eddie Shore. Bobby Hull would also be on the cusp. He left for the AHL or his numbers would've been insane.
Guys like Bossy, Jagr, Lafleur etc... incredible players who were best in the league for a time but I don't think that qualifies for generational.
