Then they'd probably look a little like these emblems created by benjamagnus—which are clever even if you don't follow hockey stuff too closely.
And if you do follow hockey, you might even think some of these are better than the original logos! Personally, I'm a fan of the Detroit Red Wings's logo reimagined with Pidgeotto above, and Brockhawks is just too good. Owen notes that the Columbus Bluedrills not only have a better logo than The Columbus Blue Jackets, but also have a better name. You be the judge, though:
Anaheim Mighty Psyducks
Boston Bruins + Ursaring
Calgary Flames + Rapidash
Carolina Ghastlycanes
Chicago Brockhawks
Columbus Bluedrills
Dallas Starmies
Nashville Predators + Raikou
Pittsburgh Empoleons
Tampa Bay Lightning + Pikachu
Vancouver Kynucks
