It is an interesting idea, but I don't know if Chicago gives up anything to move Toews at 50%. Have there ever been any rumors?
I think there is too much sentiment there to even move him or, likely ask him to waive his NMC, unless they were offering to send him to a contender at the TDL for a shot at the cup.
I think Monahan can play a role as an overpriced third line center, and at 50%, he likely has some value, so I think Calgary might be able to find a taker and possibly get a pick back, and not give us something to take him.
Unfortunately he also has a NTC, and I'd imagine he will be submitting a list this upcoming season after this Dadonov fiasco with all of the teams with enough cap space to take on his contract, which likely includes Seattle.
But at 3.2, while I don't love the idea of bringing in Monahan as a big solution, I don't hate the concept of having him around for the season as a Johansson/Jarnkrok replacement, if Francis isn't giving up much.
