Just did some Wikipedia digging...how about Louis Crusaders? Either pronounced English or French...I would recommend English as if you go the Fr route you'll have to remind each new MC/announcer you meet.

Not only includes the school name (important), is differentiated from athletics (also important), but also an homage to the crusading of St Louis IX (you could have some fun with this theme - shields, fake swords, and such).

Plays off the Penguin mascot would work too, however, you will have to do your research as there are (and were) quite a few Penguin-related teams - the Penguineers probably the most prominent at this point.

Good luck! If I can help in any way, let me know.
