I'm kind of disappointed that I can't find any crossovers for Night Hood and Harry Potter. I mean, they even got an actor with a very similar hair colour to Arsène's to play Remus in the movies, surely the visuals work. Imagine if Arsène Lupin, gentleman burglar, was a wizard and that's how he could do all that he did. Or better, he wasn't a wizard, but since his skills of thievery and disguise were just so elite, someone from the wizarding world was made to investigate if it was a wizard using their magic to mess with the muggles, and fell in love. He'd be the right age to be Remus' grandfather*, it could totally work. He doesn't even have to be Remus' actual grandfather; having awesome burglary inclined relations on the continent could only be useful to a member of the Order, during the first War against Voldemort, right? Cousins!

The closest I've found, and this is really stretching, is the Lupin family being originally from France and moving to England because Beauxbatons wouldn't accept a werewolf student and Dumbledore did.

* I judge this thusly: I am two years younger than Harry Potter. By all accounts, Lily and the Marauders seem to have been within 5 years of how old my mom was when she had me. Her mother was born during WWII. Night Hood seems to take place in the 20s, and Arsène doesn't have a kid during the show, so a child soonish after the show would be the right age to be Remus Lupin's dad's generation.
