How about a Lady Gaga musical?
I reckon it's more likely she'd write an original musical. I can totally see her collaborating with someone like Elton or Brian May and creating an odd pop/rock musical...a new rave Rocky Horror or something equally daft but probably amazing. The only way I'd like to see a jukebox musical of her stuff would be a super-pyschadelic 'Cirque du Soliel'-esque type show with remixes and instrumentals. Basically a visual-heavy trippy art installation with dance and a huge band. Kind of like those in...
