hmmm I doubt they would have one of the 3A go back to juniors after they presumably will have competed on the GP, Russia usually doesn't do that (they probably won't even have free programs that are the right length for juniors, etc although theoretically that could be changed). I do think Kanysheva will be eligible though; If my calculations are right, Polina was 14 turning 15 later that year when she won. So I think a team of Sinitsyna, Kanysheva, Tarakanova might be a possibility (obviously depends on the season but that seems like a dream team) - that would probably lock in gold well enough. Hey if only Kanysheva had stayed with Panova, we could have an all Panova team haha. Can't think of anyone other than Vasilieva who could also contend (other than those who will already be senior) but I'm probably forgetting someone.
