Please describe the new feature or change.
I was messing around with Colytra + Deeper And Darker, and I realized that the Soul Elytra from Deeper And Darker is ALMOST completely compatible with Colytra. The only thing that doesn't work is the appearance when putting it on, so I was wondering if it's possible to make the Soul Elytra on the Elytra'd chestplate have the Soul Elytra's appearance (and maybe effects and sound).

[The effects of the Soul Elytra is it emits a Sculk Shrieker-like sound along with soul particles and a vibration wave particle from behind the player.]

Please describe why you want this feature.
Because it would be amazing to retain the appearance (and possibly the effects/sounds) of the Soul Elytra when it's attached to a chestplate.
