But see, I would just say the same thing about P&P as I would about Gatsby or War and Peace. Just because it hasn't worked doesn't mean it couldn't work. And I don't see how musicalization can "inherently"cheapen anything; music has the power to add depth and nuance, and if done well, it could potentially make her language shine even more. It just hasn't yet, because nobody has done it well enough.
Or alternately, what if the adaptation were transplanted to outer space, and used bluegrass music? Like, it's ridiculous of course - and I'm not claiming that a Bluegrass Sci-fi version of Pride & Prejudice would actually be good. But that's the sort of wild re-imagining that could remove the pressure to capture the precise style of the source material, and end up being brilliant as a result. If the artist somehow saw some spiritual connection between Sci-Fi, Bluegrass, and Jane Austen, then they could make those connections and end up shedding new light on the original story. Again, this is a wild example and not one that I'm actually advocating for (although if it happened, I'd definitely go see it lol), I'm just saying that thinking outside the box can open up doors to adapting any material that seems impossible to adapt.
