It would be a cool way to explain why Mo' doesn't speaks much: he speaks french. The name, Maurice, even fits. There's historically a french-canadian population imigrating to the US in that period. "Americans of French-Canadian descent are most heavily concentrated in New England, New York State, Louisiana and the Midwest. Their ancestors mostly arrived in the United States from Quebec between 1840 and 1930 [...]". From Wikipedia. It would be cool representation. Hearing Maurice curses someone in french with a gruff voice as extra-rare voiceline would be a fun surprise.
