I think one of the biggest benefits of Azzi and Nika returning (particularly Nika) is that Evina will no longer have to function as the point guard. She is doing that now because she is the best available option, not because she has particular skills in that position or because it is her natural position. (We can thank Holly Warlick for giving her some experience in this role.)
When Nika gets back (with or without Azzi), I would expect her to be the starting PG until Paige returns. Then Evina could play 20-25 minutes at the 2 or 3, which I think is her natural position. I think her shooting (including from the 3-point line) will get MUCH better when she doesn't have the ball-handling responsibilities and can catch and shoot (or come off screens) more often.
In the near-term, I would expect to see a lineup with Nika at the 1, Caroline Ducharme at the 3, Dorka, and Liv, with the 2 position being platooned between Evina and Christyn. When Azzi comes in off the bench, Evina can potentially move to the 3 and Caroline Ducharme to the 4. I expect to see limited minutes for Azzi (maybe 15 per game) until the coaches can see how durable she is, how her defensive mobility is, and how reliable her shot is.
I don't think Caroline Ducharme will score 24 every night, or play 40 minutes very often. But I won't be surprised if she and Nika lead in minutes until Paige returns. Liv / Dorka / Aaliyah / Amari will spread out the minutes in the front court out of necessity, because they are all foul machines (Dorka less than the others). Caroline Ducharme / Evina / Christyn / Azzi will share the minutes at the 2 and 3, and they will all benefit from fewer minutes than they have had to play recently -- they will play better with fewer minutes.
PG is the only position where there is no really satisfactory backup to Nika, which is why her foot had better be very healthy and durable. In a pinch (but only then), Evina and Azzi could be used to back her up.
