C418’s Equinoxe and Excuse for New 1.17 Caves?

Hello! C418’s Equinoxe and Excuse are two beautiful pieces in Minecraft: Volume Alpha that have been left unused. They fit in well with the current Overworld music, but each have their unique flair that makes them suit well to exploring the deep underground.

Personally, I reckon Equinoxe would work perfectly for the Luscious Caves and Excuse for the Deep Dark. So, is this even possible to do? I reckon these pieces deserve it! :)
