I was actually thinking the same thing. Given the youth of the team, a veteran presence like Petry on the 2nd pairing could be good for them.
I was actually thinking Debrincat because part of me wonders what Dubas's thoughts are about Jake next off-season when he's likely due for a big raise. Could adding Smith and Debrincat make sending Jake out more palpable? Perhaps.
In this case, we could also take a dump from them as well.
Debrincat+Mattieu

Then

or similar.
