You're on the right track with naming it after players, but here's a better list.
Gretzky, Howe, Orr, Lemieux
One other positive of realignment is that ever team will have at minimum a home and home with every other team in the NHL.
Howe and Orr are good. Maybe Hull for both generations. Definitely not Lindros.
I just got stuck in the generation of hockey I remember the most. Be happy I didn't suggest Mike Richter.
