As the title suggests, a lot of old emotes could have a fun use as either dash or glide animations (hopefully ones people can easily get, unlike the Hover Dash).
So far there are two emotes that I have that might work well for mobility options:
A pose from Drift in Space for a glide animation
The male side of On All Fours for a dash animation
If anyone else has ideas of converting old emotes to NGS mobility animations, feel free to list them here.
