I get you're a pens fan but Konecny > Rust, Provorov > Dumoulin, Hayes > Blueger, Myers > Pettersson, and Hart > Jarry and Murray
You should do lines like this:

Giroux - Crosby - Konecny
Guentzel - Malkin - Voracek
Zucker - Couturier - Rust
JVR - Hayes - Hornqvist

Provorov - Letang
Dumoulin - Marino
Sanheim - Myers

Hart
Jarry

Why mess up Zuck+Sid chemistry? GMR was one of the BEST lines in hockey, why put Voracek there?
Dumo - Letang is one of the better pairs in the NHL, why break that up?
While I agree Hayes > Blug I obviously have a Pens bias like you said lol
Pettersson and Myers are interchangeable I'd say but I love Petes game when he's on, so I'll keep him there. Myers to make the LD-RD balance better does make sense though.
Jarry > Hart right now IMO but Hart potential >

Crosby has chemistry with everyone, whether Zucker's there or not is irrelevant, but Giroux is the best LW across both of these teams and should play there. Konecny is IMO the best RW and has the highest ceiling as well.
I put Rust on the 3rd line because his 2-way play compliments Couturier's better then Malkin's. Also Voracek's offensive play-making ability will compliment Guentzel's goal scoring tough and Malkin's offensive prowess much better than Rust's.
Hayes is a solid 2-way center as well as being more offensively skilled than Blueger.

You can keep Dumoulin with Letang but there is a big skill difference in him and Provorov. This entire situation is hypothetical anyways so without actual trial there is no way of saying Prov wouldn't be the better line mate, but by skill alone he is superior.
I should clarify, Sanheim is better than Pettersson. Sanheim is naturally a LD but is listed as RD on CF for some reason. that leaves a hole at RD where Myers would fill as he is the next best option.
Before the loss to Boston the other day Hart was on a 7 game win streak and has a 92.4 SV% in his last 10 games. Hart is certainly the better goalie right now. The only losses he has are to Tampa and Boston
