Sure? Why shouldn't they be allowed to do it? It's an amateur production, thus people should expect the so-called "butchering" (though I have seen plenty of amateur shows that were good).
High schools can already do great shows such as Helly Dolly, Mame, Seussical, Peter Pan, Little Shop of Horrors, Annie, Guys & Dolls, Into The Woods, Parade, Ragtime, Company, Damn Yankees, Fantastiks, Fiddler, How to Succeed, Music Man, Les Mis, Pippin, 1776, Good Man Charlie Brown, West Side Story, etc. Why not AIDA and BEUTY AND THE BEAST?
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
