Is it possible to change the music in quest mods to something else?

I downloaded a quest mod, The Cathedral on Steam for Oldrim, and it’s pretty good but the music isn’t. I feel it would benefit much more from an ambient soundtrack. I was wondering if it’s possible to add my own music to this particular mod instead of using its own.

Important: the music for the main game must be unchanged and should play as normal when outside of the mod area. Thanks for any ideas 🙂
