Czechia only gets their team together for the Olympics plus a few days prior; Sapovalivova will be arriving next year and has already said how much she is looking forward to it.
As for the rest, there's no Olympic centralization next year with the PWHL existing, so I'd find it highly unlikely any of the college players would take the year off without anywhere else to play. It's likely teams will have to play down for three weekends.
With opening ceremonies on the 6th, the optimistic view is that they would leave immediately following the games on 1/30-1/31 and would miss 3 weekends; 2/6-2/7, 2/13-2/14, and 2/20-2/21. That would bring them back for the first round of the WCHA playoffs in a normally scheduled year.
Let's take the middle view and say that Eden, Edwards, Simms, Harvey, and Sapavalivova make teams. That means for three weeks we'd have to make do (if healthy) with:
F: Hall, K. Gorbatenko, Enright, Scannell, McCarthy, Halverson, Zilisch, Vasseur, Pieckenhagen, N. Gorbatenko
D: Jungels, Murphy, Potter, Venusio, Jones, R. Gorbatenko, Bickett
G: MacNaughton, Stewart, Baker
I think we'll manage.
