Mamma Mia, Guys and Dolls, My Fair Lady, 42nd Street, Seussical, The Producers, Cinderella, and Dreamgirls could be fun. I'd also love to see a more dramatic musical, such as Ragtime, Evita, or Fiddler On The Roof. I'm surprised we haven't gotten something by Andrew Lloyd Webber or a Disney musical on ABC. I could see Mary Poppins or The Little Mermaid come to life easily.
Honestly, I wouldn't mind the Lea Michele-"Funny Girl" thing finally coming to fruition as a live television musical as opposed to a stage version. If it's destined to happen, this os a way to go about it. Plus, she and Ryan Murphy have ties to Fox.
Or just film Hamilton. Easy enough.
