Should I start a Harry Potter Club at my high school?

I am pretty obsessed with Harry Potter (haha) and I have been thinking about the possibility of starting a club devoted to it at my high school during my senior year. But I can't imagine people at my school flocking to a Harry Potter club, because the people at my school are, frankly, kind of stupid (for the most part). I could only think of two people I've encountered at my school joining an HP club. I could think of a teacher that might want to sponsor the club, but I have not approached her with the idea yet. This teacher is kind of mean, but I am taking her AP English Lit. class next year, so that might help. I'm not very popular at my school already, so I wonder if starting such a club would hurt my chances of making a lot of friends this year. I don't want to be known by girls as "that guy who's obsessed with Harry Potter", either.

I have started a school club before at my old school in 9th grade, but it wasn't very successful. I would hate for that to happen with this club again, so I wonder if I should even try starting it. Can someone help me? Thanks!

P.S. Also, what could we do in a Harry Potter club? Any ideas are appreciated!
