Robertson - Hintz - Stankhoven

Benn - Johnston - Bourque
Dadonov - Steel - Lind
Heiskanen - Dumba
Harley - Lybushkin
Lindell - Lundqvist
I would put Bourque up on the top line, and Stank back with Wyatt and Jamie.....a proven combo. Change as little as possible. Heck, even Dads might end up on the top line from time to time.
The D pairs are pretty good. If Esa was a righty, he should switch to second pair. Nils and Ilya would make up the third pair, lightly used. Brendan Smith is the no. 7, until about 10 games in, 20 tops, when Lian comes in to replace Nils.
In fact, I predict a slow start, made a bit better by a fairly easy first month schedule. In the old days, GM's looked at their squads 20 games/25% of the way into the season and if not doing well, go for the shakeup then.
