How to convince our Drama Club director...?

My drama club director is highly highly highly highly highly against doing the show that we, the seniors, and everyone else in the drama club wants to do very badly. The show is not in any way inappropriate, but it is a Disney show. I think the reason she is so strongly against it is because our former (HORRIBLE) director did mainly disney shows, although this one has never been done. The show is just so...perfect.

I've already decided that by talking about it further will only make it much much much worse, and that I won't try until the time comes. I am more than willing to put toward all of my paychecks from now until then to the show so no money will come out of the drama club budget to do it. I am willing to put everything I have towards this show. I'm that strong and dedicated to doing it. I don't want to do any other show, and I already feel heartbroken enough for not being able to do it at this point. I don't know what else I can put forward when the time comes to be able to do this, which is why I'm asking this:

What advice do you all have on raising our chances on being able to do this show? I'll listen to anything at this point.
