Lots of skaters train a bit in ballet without the results being clear. The most likely reason? They don't do enough of it. Not enough so that it's automatic and entrenched in their movement. It may also be because they didn't start doing it young enough. Or their ballet instructors aren't disciplinarian enough. Or it could just be that some people aren't ever going to absorb the ballet aesthetic.
I am OK with that though. I don't think one needs to be genuinely balletic to be graceful, moving, elegant and entertaining on ice. And I think a lot of ballet's philosophy of movement simply wouldn't work in skating, where the physics is different.
I only know of two examples, but so far I like what training in modern dance has done for skaters more so than ballet training. Savchenko/Szolkowy did some modern dance, and it comes off beautifully in their FS, but especially well in their exhibition number to Lang Lang. And modern dance training has especially improved Patrick Chan, whom I find a lot more expressive with his entire body now. I think the benefits of traditional ballet training, with its emphasis on line and posture being the most applicable to skating, is something that can be conveyed just as well on ice. On the other hand, modern dance, where its emphasis is more on expressing oneself, digging in and reaching out emotionally, can really help skaters become more honest in their movement.
So rather than ape ballet, which may or may not be the right style for Gracie, I'd rather see her get some form of dance training that helps her find her own style. I think that will help her reach the audience the most.
