The right composer for 'Brokeback Mountain' the opera?

Good idea: turn Annie Proulx's short story "Brokeback Mountain" into an opera. The plot is a great fit, certainly better than "Dead Man Walking" or "The Great Gatsby" (and we will soon see about "Grapes of Wrath" at Pittsburgh Opera this fall), and the story would thrust opera into an active dissussion of a contemporary issue (which is also the case with "Dead Man Walking" and "Nixon and China" and others, but the more the better to make the artform relevant). New York City Opera will produce "Brokeback Mountain" (I would assume with the same name) for spring 2013. Congrats to the company  on the choice.

Not so good idea: Have Charles Wuorinen compose the music. Now, while he has extensive experience with vocal music and is an esteemed member of the American composing scene with many excellent works to his credit, his compositional aesthetic is, in my opinion, hardly accessible or overly melodic. His style is often called "maximalist," and but to me, it often comes across as overly complex for the sake of it. Since "Brokeback Mountain" will need to appeal to a wide range of patrons -- many of whom did not like the modernist and post-modernist eras in music and who won't be forgiving if Wuorninen softens his approach but is still not sonically pleasing to them -- my guess is this choice will lead to problems. I hope to be proven wrong, but I have a sinking feeling about this one.
