I think so to, but I think it’s nevertheless a related and also interesting subject if film scores have been repurposed or adapted for the ballet.
Sure, as you said you can use basically everything for a ballet and that is frequently done, even with classial stuff.
Also, depending on what you composer, a ballet is more difficult to perform than a symphony, as you don’t just need the music, you also need a choreography. And then an orchestra and dancers, so it adds up.
Yeah, that’s of course why ballet composers regulary created concert suites. And some ballets like Prokofiev’s ROMEO & JULIET are 2.5 hours in their original version. Overload for many without a ballet iself unless you need it “complete and chronological” 🙂
