Describe the feature you have in mind.

currently, the jetpack model pulls the model and texture for the copper backtank armor and the netherite backtank armor for each respective jetpack. I would like to see the jetpacks use unique textures and models Instead.

Does this solve a particular problem?

I was making a personal modpack where I was trying to turn the netherite jetpack Into a different armor type only to be stopped by the shared model. this would allow resource pack creators to give custom textures to the jetpack armors and allow modpack creators to recontextualize the jetpacks.
