Sasha: yeah with a 3A and 5 quads landed of course she could outscore Darya with 3A and 4S (idk how many of the two she would put). But she has never landed a 3A nor 5 quads cleanly as a senior in one competition leave alone both at once. And all other aspects of her skating are severely inferior to Darya.
Anna: I'm not so sure if two 4F and one 4Lz by her would outscore a let's say two 3A and two/one 4S Darya. Considering Darya's spins and SS are arguably better. Of course she would be held up in PCS against a fresh junior in the beginning but even there we've seen how fast the Russian Fed changes favorites very quickly according to how the wind blows. And things get decided at Russian Nationals.
Alena: No. Even with three 3A in 2020 shape she can't compete with a hypothetical Darya that has that same 3A PLUS a quad.
But this of course is all just speculation based on the hypothesis that Darya does actually acquire any ultra-c at all.
Daria would probably do a 3A in the SP, and a 4S, 3A in the FS. (That would probably be the most they can hope for and she'll need to be consistent and clean. That will be hard initially as she'll need them roughly consistent from the get go. Most of the others with "ultra-c" elements have had them for at least 2 years. They won't push for two 3A's in the FS, considering both jumps are soo new and she would have to do one in combo AND a new 4S.)
Looking at just the FS (because ultimately that's where all the movement comes):
Daria: She has a BV of 74.95. She'll probably do something like 4S, 3A, 3Lz+2T, 3Lo // 3Lz+1Eu+3S x, 3F+3T x, 3F x.
Now we already know Sasha won't attempt anything less than 4 quads. And she HAS landed 4 in competition. That alone is enough to beat Daria.
Sasha (4 quad BV): There are a million and one things Sasha could attempt but for fun, she'll have a BV of around 89.40. Something like this: 4S (or 4F), 4Lz, 4T+3T, 2A // 4T+1Eu+3S x, 3Lz+3Lo x, 3Lz x. Fun fact, she actually has landed this in competition.
Daria's spins and steps are better than Sasha. Sasha had F edge issues; however, Daria has Lz edge issues and hers are often worse. They'll actually be fairly close PCS wise.
And Sasha will also probably go for more, so she'll be able to afford more mistakes.
Anna:
Now this is the fun part:
Anna (1 quad BV): 73.68. That would be this: 4F (or 4Lz), 3F+3T, 2A, 2A // 3Lz x, 3F+1Eu+3S x, 3Lz+3Lo x. (That's her World's FS layout.)
Already you can see that Anna makes up a lot of the difference even with "only" one quad and 2 2As.
Anna (2 quad BV): 81.88 That would be: 4Lz, 4F, 3F+3T, 2A // 3Lz+3Lo x, 3F+1Eu+3S x, 3Lz x. (This is her RusNats layout and she's been perfect on it.)
Here you can see that by this point Anna's already going to outscore Daria in the FS.
Now let's look at PCS, etc. Both of them have good spins (Anna's at World's were wonky but she fundamentally has them and if we're giving Daria 3 jumps she's never even attempted in competition one of which she's never landed in practice, we'll give Anna her spins.) Both of them are going to get their levels on steps. So there will be essentially no difference there. Both do have edge issues but Anna's won't be called, domestically or internationally and hers is a !. Daria's is closer to an e, so if panels are calling edges, it'll hurt Daria more. Second of all, Anna is the reigning World champion and 3x Russian Champion, and both international judges and domestic judges love her.. The Fed even when she was struggling didn't abandon her. Internationally as well she got incredible scores. Judges love Daria, yes, but she's a first year senior. No one has a stronger resume than Anna right now.
Anna (3 quad BV): 87.58 (That would be a 4Lz, 4F+3T, 4F, 2A // 3Lz+3Lo x, 3F+1Eu+3S x, 3Lz x)
If clean, and honesty that's more likely for Anna than Daria, Anna will win the FS and as you'll see completely eliminate any SP advantage Daria will have.
Aliona: At 2019-2020 form, she'll have a BV of 70.15. That would be 3A+2T, 3A, 2A, 3Lo // 3F+3T x, 3F+1Eu+3S x, 3Lz x.
Aliona's BV is already not that much lower and she more than any of the above skaters will get points on GOE, spins, step sequences, etc. Remember Aliona will a BV of significantly lower than Anna and Sasha outscored them when clean. And Daria will come in with a reputation that'll be around first year Anna and Sasha. Daria won't have ANY spins or steps advantage against Aliona. And as for PCS, Aliona will have higher PCS than everyone else (although Anna and Kamila very well might be as high.)
But the 3A in the SP, I can hear you saying.
Okay but let's look at that:
Daria's SP BV and layout with a 3A: 37.65 3A, 3Lz // 3F+3T x
Sasha's SP BV and layout with a 3A (she hasn't landed this cleanly in competition but she HAS in practice): 37.71 3A, 3F // 3Lz+3T x (She could also do a 3Lz+3Lo here maybe)
Anna's SP BV and layout: 33.78 2A, 3F // 3Lz+3Lo x
(There's only a 4 point difference here and Anna's 2 quad BV FS already makes that up. We also know she's scored 80.00 points internationally without a 3A. And she has beaten 3A programs both domestically and internationally)
Aliona's SP BV and layout (2019 - 2020 form): 3A, 3Lz // 3F+3T x
(Same as Daria except we already know Aliona can score 85+ points internationally on this. Daria will probably be around 79-82/83, internationally.)
All that to say, yes, Sasha, Anna, and Aliona can outscore that. And Anna and Aliona can even have a tech disadvantage and still do it.
