So far the situation looks like whoever is not on top 24 SB list won't get a GP assignment (with the exception of Anna with her WR), so Konstantinova and Fedichkina won't be much of a factor when they move up, they will get Challengers events and a host spot at Rostelecom if lucky. This can change for Stasya as she still has one CS event to improve her scores (unless they send her to JW again with placing her above first year juniors at JNats, I hope not), but she needs two clean or at least almost clean skates which is unlikely.
With Gubanova, Panenkova, Samodurova and maybe even Gulyakova, a lot will depend on if they make it to Junior Worlds and how they place there if they do. Gubanova needs to make it to JW AND to get top 24 SB scores there to move up as she is not age eligible yet to get her SB on Challengers events. Even if the RusFed won't stop her, I doubt she and her coach want to move up when not guaranteed any GP assignment and with a chance to get JGP. Same with Gulyakova. As for Samodurova and Panenkova, I think it's up to their coaches to decide with the federation having a word too, but I doubt they will stop either of them as both are consistent, Panenkova is Eteri's girl wich means a big scoring potential, and Samodurova is Mishin's main hope
Think that if Samodurova/Panenkova/whoever get a guaranteed GP slot they should always grab it while they can, they may be like gold dust in coming seasons. Also it opens up the world of further ranking points because they may be able to do 2 GPs. Ranking points are very useful but as far as I can see you'll never get enough on the challengers to get a top 24 WR e.g. if you were to win 4 in 2 years you'd get 1020 ranking points after taking account of the 70% reduction for the previous year (600 + 600 * 0.7), but 1500 or so was needed this year. However start doing GPs and there's more chance of points available even if you don't reach the Championships and the really big points on offer there.
Incidentally it may be that Anna P is not as guaranteed a WR slot as you may think. This year Angelina Kuchvalska just missed out on a GP slot (I was doing predictions so saw exactly what happened) and she had just over 1500 points (hasn't gained any this year so you can how many she had), but Anna after the 70% reduction will only have just over 1400 so she isn't guaranteed at all. Also Mao Asada wasn't removed from the World Rankings before the selection meeting even though she'd already announced her retirement, so it may be that that retirees after the Olympics won't be removed, we'll have to see, any retirements may be a little more notice though. Also points have been more spread out on the GP series this year as more and more ladies come through so it may be less points are needed this year than in previous, but as I say Anna isn't necessarily guaranteed at all.
