Thank you for your question!Question for those who much more knowledgeable than me about ballet....
I haven't seen Oksana Baiul referenced yet in this discussion. I remember her doing a program (maybe an exhibition) to "The Swan". I thought she looked quite balletic in her movements. Would she qualify as a "balletic skater", or was it just to my untrained eye?
Also, I remember Yukari Nakano doing a SP in the late 2000's to "Giselle" where part of the footwork sequence was definitely from the ballet. I wouldn't qualify her as "balletic" (although I thought she was very artistic), but that part of the program was.
Thanks.
I'm not the most knowledgeable ballet person in this thread either but I have thought about referencing Oksana. Here is her Swan Lake short program, Lillehammer, 1994, with some bent knees (that's why I actually prefer her musical-themed free skate where her pose with bent knees looks more appropriate to me). But she is definitely an actress on ice, so involved emotionally!
And here is her exhibition, The Swan:
