Yeah, but they probably would want a different feel altogether for a reboot. Probably a minimalist score. Batman's 'theme' music in the recent films, for example, is like three notes, and that's it. and joker's theme is, uh, one note. Still very effective.
The problem is that our culture has almost beyond memorable themes
The last decent movie score to me was Gladiator, and this was 11 years ago.
