Laughing at all the indignant responses in this thread.
Average regular season viewership per game, 2020 - 2021 regular season:
NBA: 1,340,000
NHL: 391,000
So no, the NHL doesn't have nearly enough fans to buy that many varieties of jerseys, regardless of how cool they'd look. Maybe one day the NHL will be able to fit in its big-boy britches - and then sell them.
