S Rank Theme

Lately I've been listening to the FFXII OST while playing the game, because I like the variation in music when traveling around. Anyways, while fighting The Pale Rider, just as it was pulled, suddenly Esper came on and the entire fight felt amazing just because of the music. Suddenly, it was an epic battle between a giant and the world, not just another S Rank spam. Is there any chance we could get 1-3 S Rank themes that could play at random when fighting S Ranks? I think it'd really make them feel like genuine boss fights!

Likewise, for those maps that have special FATEs, you could play a theme that goes throughout the entire map to match the special weather that triggers said special FATE. Atmosphere ftw. :)
