Palat-Hughes-Bratt
Tatar-Hischier-Zetterlund
Sharangovich-Haula-Mercer
Wood-McLeod-Holtz
Is what I would try out on the forward side of things with Palat back. While not a center, I think Palat can do the exact things Lindy attempted to detail that Haula brings to Jack's line. At the same time, Haula has possessed the puck well enough that I think he could hopefully bring a spark to Rango and Mercer, who need it.
I like what Tatar and Zetterlund have done together with Nico previously, so give him another shot. And Wood-McLeod-Holtz has looked decent enough that I'm good with keeping them together while giving Holtz more PP time. When Bastian is healthy as it appears he could return, you look to send Holtz back to Utica to get top minutes or sit Zetterlund if he isn't producing still.
I'm a Boqvist fan, I like him. But he doesn't have a spot in this lineup at the moment.
As for defense, while it was their worst game of the season, I think Siegenthaler-Hamilton need to stay together until Marino is back at least.
Siegenthaler-Hamilton
Okhotiuk-Severson
Graves-Smith
Deploy them how you want in the mean time, but I'm not a fan of Graves and Severson on the same pairing so I think you need to split them up and insert Okhotiuk for Bahl who has had 2 miserable performances in the last 3 games.
