Butterfly twist spin
So in figure skating, there's the butterfly spin:
In martial arts, there's the butterfly kick:
In martial arts, however, there's also the butterfly twist, where the person brings the leg together for additional rotation prior to opening up for the landing, and land on the takeoff leg rather than the free leg:
There are also moves along this line which are just adding to the number of rotations in midair, such as the hypertwist (landing on the free leg) and the double butterfly twist:
My question is, would it be possible to incorporate those rotations into the butterfly spin? If so, then why don't people do it? (I assume it adds to the difficulty.) If not, then why not?
My guess is that the two moves, though similar in form, are working at cross purposes; for a butterfly spin, it's to get rotation for the subsequent spin, while for a butterfly twist, the goal is to get height (to have enough time to do the rotation), so you're kind of driving the jump in different directions. But it seems like you should in principle be able to get enough height for a butterfly twist or a hypertwist and still have enough rotation for the spin afterwards.
I'd try it myself but knowing me I'd get my skates tangled together in the air

Here's Robert Wagenhoffer, who did a butterfly kick type maneuver at the end of his programs
Lately I've been preoccupied with other things so haven't looked much at skating, but I came across this video which is the closest I've found to what I had in mind:
He had to put his hands down in the end, but otherwise, his takeoff form was pretty good (he could probably have wrapped his feet more in the air though to get around faster).
I guess so if it's doable, then the next question is why more elite skaters don't do this move, since they obviously have the height for good butterfly spins?
