That is certainly a good point, that by broadening the scope it would invite more participation. My stumbling block there is that this is really a Harry Potter community. If another community or platform were to host an event promoting diversity in fandom representations, I would be very happy to promote it here. But I am not sure that turning this into a multifandom community is necessarily a positive one for the community as a whole. It just seems to me like that would be equal to saying there's not enough interest in the HP fandom to sustain this community. Which may be the case.
