I think most choreographers are used to choreographing for skaters who sometimes compete against each other. Just like coaches coach multiple skaters who compete against each other, like Eteri does.
Of course, not all coaches are going to get along with all choreographers, and some choreographers insist on having more of a say in the final product than others, which probably wouldn't jive well with Eteri. But I do think the majority of choreographers realize that choreography is going to change to suit the technical content and what the skater is capable of. (I don't think most choreographers get too involved with costume/styling decisions.)
I'll admit I just don't like Daniil's style re: the amount of transitions, arm movements, etc. in his programs, and I'd love to see Alina with something that emphasizes her line and more long-held movements. That said, I do think Daniil has generally done a better job choreographing for Kostornaia, Shcherbakova, and Trusova than he has for Alina. Each girl has a distinctive style that he emphasizes and that suits them, and their programs overall come off as less busy/cluttered than Alina's. The second half of the Don Quixote LP is, IMO, the best job he has done choreographing for Alina that captured a sense of energy and balletic quality. I just don't think his programs highlight her strengths/potential strengths.
ETA: I'm no Averkbukh fan, but I am curious about what he would give Alina, if given the opportunity. It doesn't have to be a non-Russian choreographer. Just someone other than Daniil I would like to see.
