They used to have an Adapted Score category, mashed in with Song Score (original or adapted). Stranger things have happened.
Adapted Score Oscar-winners of the past include:
The Music Man (the first year they had the category of "adapted" score for 1962)
Irma La Douce (which threw out all the songs but used them as underscoring)
My Fair Lady
Sound of Music
A Funny Thing Happened ...
Camelot
Then in 1968, they realized this award was going almost exclusively to musical films (with the exception of Irma), so they changed the category to "Scoring of a Musical Picture, Original or Adaptation." By doing that, they eliminated any non-musical films with adapted scores. The other music category was Best Original Score.
Then, for 1971, it changed again, realizing that they had shut out non-musical adapted scores from any recognition. So the category became Best Original Song Score and Adaptation (which included non-musical films as well).
Winners included:
Fiddler on the Roof (not an original song score, but an adapted score, and it was John Williams first Oscar)
Cabaret (adapted musical score by Ralph Burns)
The Sting (Scott Joplin adapted by Marvin Hamlisch)
The Great Gatsby (adapted music by Nelson Riddle)
Barry Lyndon (adapted music by Leonard Rosenman)
Bound For Glory (adapted music by Leonard Rosenman)
A Little Night Music (adapted by Jonathan Tunick)
The Buddy Holly Story (adapted by Joe Renzetti)
All That Jazz (adapted by Ralph Burns)
Then they killed the category for two years in the early '80s, only to bring it back again for 1982:
Victor Victoria (original song score by Leslie Bricusse and Henry Mancini)
Yentl (original song score by Michel Legrand and Marilyn & Alan Bergman)
Then they knocked off the "adapted" part again, and made it Best Original Song Score for one year (the winner was Purple Rain) before they killed the category.
They finally added a second "Musical or Comedy Score," separating that from Dramatic Score, for few years in the '90s, during the heyday of Disney's animated "musicals," which was taking home the Best Original Score award almost every time. They thought it was now being unfair to Dramatic scores to have them compete in the same category.
I think it would be worth a try to revise it again. I also think it's a worthy category for recognition since so many songs in films are adapted these days. But I agree it'll never happen. The studios would freak out over the "nominees to be determined" part, having to submit who is credited for the adapted song: performer, producer, director, writer, arranger, etc. It can't be all of them and shouldn't be. It should be the 1-3 people who are responsible for having that song in the film presented in such a way.
