I'm open minded on this and will respond to them individually.
Conn Smythe was an asshole on a lot of levels, but this is a weak premise for changing the name of the trophy. Presumably this complaint comes from his famous quote about wishing Herb Carnegie were white so he could be signed to a contract -- at a time when nobody else would sign Carnegie either. Smythe simply pointed to the root of the problem in such a way as to be quoted about it later. There are plenty of things to hate about this guy, but he was not some slave owner or Klan member. And he was a figure actually worthy of remembrance from a hockey standpoint. Keeping this one is perfectly fine.
Art Ross was more than "an innovator", he was one of the most influential figures in hockey history. He was also one of the best hockey players in the world before the NHL existed, and went on to coach in the NHL for 20 years. It's laughable to suggest that his NHL scoring record should be the thing we think about when we think of Art Ross. Of all the people on this list, he is probably top-3 in terms of deserving it.
This one has some merit. Norris has a trophy named after him because his money bankrolled the early NHL and his family went on to run the league from the inside out like a syndicate. He is not a figure who needs a trophy named after him. Changing it would be no major loss.
The Hart was actually named after Cecil's father, who donated it. David Hart is not even close to being a trophy-worthy name in the history of the league. Even Cecil is just a footnote. People would lose their minds because of the break with tradition, but it would be justifiable to move on from this one.
Agreed, and it should specifically be on the one awarded by the NHLPA.
No, he played in over 200 games over 9 seasons. He was the first great goalie in the league and had a tragic story. There's no reason to change this.
Which is fair enough, no reason to change this one.
That's pretty much the entire case for him. He was iconic as the first President. There have been more deserving figures, but there's nothing saying Calder doesn't deserve it.
Indeed, and he's an important figure, but Selke is a weak one. He knew the right people and GM'ed the right organization. Good guy, important to a certain point, but not someone who needs a trophy named after him.
This one is absurd and the low-hanging fruit if we're going to change something. Naming the trophy after him was basically a retirement gift from his golfing buddies. There is zero reason to name a trophy after an otherwise unremarkable team president.
Agreed.
Based on the above, I would suggest the following:
James Norris -> Bobby Orr (and do it before he dies, damn it)
Hart Memorial -> Wayne Gretzky
Frank Selke -> Gordie Howe
William Jennings -> Simply decommission it and leave it blank for future use.
