Would it be possible to add your own custom music to Vilja's playable music?

I love my follower Vilja, and I was wondering if it was possible to import my own music into her playable songs that she can play with her instruments. Lore/immersion wise it would be a bit strange, but it would be cool nonetheless. Are there any guides I could follow to get this set up? Quick google search provided no results for importing music into a follower. If this is possible, could you share some links to get me started in learning how?

 

Edit: This is probably the first song I would add (ESO Beauty of Dawn)

Anyone know if this is possible? It's been on my mind for awhile now.
