See I'd argue that an indoor queue is less authentic (although it's more comfortable and in all other ways makes more sense). The "real" Ollivander's as presented in the books and movies is a small store that you go into directly from the street. Once inside there's really just the one room (which looks a lot like the one room in Hogsmeade right now). That's all there is to it.
Somehow in the books and movies there is never a crowd or a line, so you're able to just go up to the counter and have assistance in the wand-choosing process. Obviously that can't be replicated, (and I think Hogsmeade is the closest it can be), but it will still be weird to enter through a shop, get into a line, then go into a showroom (that's supposed to be the shop you entered through), and then exit via the same shop you entered through.
I'm sure that the theming of the queue will be detailed and immersive and all those other buzzwords, and it might be great, but it won't be like Ollivander's in the books or movies.
