Might be more work than it's worth, but

While you are using the fly power, you're able to sit/stand/do a few select emotes, like floating a /e lotus sitting position.

Is it possible for this to be carried over to the magic carpet/void skiff/etc. ?

It sounds like a lot of work to me, but I am also not the devs and don't know how much work would need to be put in to allow the ability to emote while maintaining the illusion of "sitting" on said platforms, or doing a couple other various emotes/stances such as /e lookup or /e villainstance2 while flying?

I think the problem is that the magic carpet et al are themselves emotes. I'm not sure.
