Idea for skins

I had this idea driving to work today. Feel free to give thoughts about it. What are your opinions on adding music into the game for certain skins involving music, pentakill specifically came to mind. My idea was adding an optional button or mechanic like DJ Sona has for listening to her music, but for other skins. As an example, say I'm playing karthus or Yorick or something with a pentakill skin, I could hit a button and listen to like Lightbringer and a few other songs for karthus and like mortal reminder and others for Yorick or mordekaiser. I also thought about an Easter egg or something if you match skins as a team, like an all KDA or Project or Pentakill skinned team, your team gets a spawn in animation for that game or special music for the whole team or something like that. My idea is that these animations and music are included with purchase of the skin. This would promote playing with friends or at least a premade group. It would have no impact on gameplay just user experience. Please vote, leave a comment, and/or upvote the post. Thank you.
