I don't think she has a salchow and her axel is abismal.It's a little unfair to compare a program that has been allowed to develop and flourish (Mao's Swan Lake) compared to Yu-Na's undercooked programs. It will depend on how Yu-Na sells it in the end; she said herself she wasn't focussing on artistry on her outings this season. Just focusing on her technical elements.
As for Gao, I really hope she continues to improve. Her layout should be:
3F-3T
3Lo
2A-2T
3F
3S
3Lo
2A (or something to this effect).
Her Lz isn't worth it; she should put another 3Lo because that is at least a solid jump for her.
I'd leave the lutz, but work on improving the axel and as you said, put in 2 of them to allow for a 3/3
3 flip/3 toe
3 lutz
3 flip
2 axel
3 loop/2toe/2loop
3loop
2 axel/2loop
