Here's a wild stab at it...
Baertschi - Horvat - Virtanen
Prust - Vey - Dorsett
Gaunce - McCann - Hansen
Kenins - Cracknell - Grenier
Edler - Tanev
Bartkowski - Corrado
Hutton - Biega
Miller
Markstrom
If Vey is on this roster, that will be his most likely line-up, so he has to make it work. Baertschi with an opportunity to make some chemistry with Horvat. Ditto goes for Virtanen, who you can't switch with Hansen since that leaves 3 rookies on one line, which won't realistically happen. That leaves you with your fourth line.
On defense, I was tempted to play Hutton with Tanev, but you need that top shutdown pairing. If Corrado is to outplay Hutton, it'll be on a line with Bartkowski or Sbisa, so that fills the rest out.
