Custom Chase/Survivor Sacrifice Themes

Hey guys,
So I listened to Pyramid Head's PTB chase theme (again) and really miss this version. I enjoy it more than the live one, personally. I was wondering what everyone thought if there were custom chase themes based on the skin you're wearing.
Let's say Immolation PH gets his old PTB chase theme. While it is similar to live, it is still different a bit different and unique. There are a few other killers that have had changes from PTB chase themes, such as Demo. Certain skins could use those old chase themes, but others keep the live versions. It would make more skins unique and even more worth buying to me.
Trapper's Krampus skin or Clown's Santa skin could have more "Christmas" sounding chase themes that still sound similar to their current themes (maybe not Trapper, as his is base chase theme. It could also sound similar to 2018 Winter event home screen theme). This prevents confusion on who the killer is, because it sounds similar to what they already have.
As for survivors, I think it would be really cool to make them more unique than just being a different model. Each survivor could have a custom sacrifice theme. When Bill is sacrificed, he could hear the L4D game over theme, Cheryl could hear the static, like in the SH series with the radios, etc. It would make each character more personal and unique. Not just the same play style, different model.
What do you all think?
