Total List of eligible players:
Voit
Grebyonkin
Kressler
Minten
Moldenhauer
Lisowsky
Voit and Minten are the only ones with decent to good chances
Grebyonkin/Kressler are playing/producing well enough that in a pure meritocracy they should get consideration, but neither has much of/any track record with the top level nation programs so it's highly unlikely. Kressler just doesn't have the track record playing at this level. Greb on the other hand was one of the best 03's in the MHL last year, and is top 9 in U20 KHL scoring this year- so there's a chance.
Moldenhauer would be getting consideration if he were American, but double whammy of no track record + USHL says no chance for Canada.
Lisowsky simply isn't that tier of player right now.
Edit- living in a hockey bubble, does Greb even have a team to play for or is Russia still banned?
