request: origins mod integration

[ChloeIsNobody]

the origins mod for fabric has become very popular recently, and it allows players to use an origin with a slow falling ability and an origin with built-in elytra wings. I was wondering if it would be possible to automatically set the stance to avian when a player was using either the avian or elytrian origins. Ideally, it would be set automatically when the player has a power of the power type origins:modify_falling and fall damage set to false, or of the power type origins:elytra_flight and render_elytra set to true. However, I do not know how possible the latter option is. Or, if neither of those two things are feasible, can there be a command to set the player's stance? Either way, thank you, and have a nice day!
