Sweeney Todd: Appropriate for a high school to put on for the community?

My high school is trying to come up with a good show to do this next spring, and one suggestion we got was Sweeney Todd. I, personally, am obsessed with this play, and my director is, too. The music is phenomenal, and the story is amazing. I know there's a PG version out, but most people in my community are a bit on edge about it. So, do you think a PG version of Sweeney Todd would be appropriate for a high school cast to put on? I mean, we did Grease last year (The edited, high school version, which quite frankly sucked) but most people didn't go or left through half of it because they were scared of what content we added in (I mean, we went with the original version of "Look at Me, I'm Sandra Dee", and we ad-libbed a good bit of Rizzo's and Kenickie's dialogue, considering it was cut out of our scripts). What do you think? I, personally, would leap at the chance at doing Sweeney Todd (It's been my dream to play Mrs. Lovett), and I realize it'd be nice to do a show for the people of all ages to enjoy, but I don't want to be stuck doing Disney and fairytale plays for the rest of my time in high school.
