Just as an example, here's what two iHeartRadio stations have for their holiday shows:
Z100(NYC): Taylor Swift, Camila Cabello, Jonas Brothers, Lizzo, Lewis Capaldi, Halsey, 5 Seconds of Summer, Niall Horan, Dan & Shay, Fletcher and Monsta X.
102.7 Kiss FM(LA): Katy Perry, Billie Eilish, BTS, Sam Smith, Camila Cabello, Halsey, French Montana, Lizzo and Normani.
Had Kiss 98.5 been able to do Kissmas Bash, I could easily see either Camila, Billie or Halsey headlining it. Plus, add in Capaldi, 5SOS, Lizzo and maybe another act or two and you'd have a decent show. That said, this is simply speculation and nothing more.
