If they do another one next year (or whenever), it will be because this one "worked" for them. So don't look for any changes in perception of why it worked, meaning ratings, not quality.
So you'll have a show that everybody knows, or at least thinks they know because they've all seen the movie. That would be Grease or Guys and Dolls (oops, not family enough) or Annie again. Or maybe Grease. Or perhaps Grease. (And really, nobody listens to the lyrics enough to realize that they swear in it.)
And it will star someone that everybody knows. Whether they can sing, dance, or even speak four words in a row.
So you won't see A Little Night Music starring Carrie Underwood, but you also won't see Grease starring Laura Benanti. The show AND the name have to be easily recognizable.
