Considering Pittsburgh loses a few more games before the deadline, they will give up an old [D] like Boucher, in return for a draft pick. It works out for Montreal, since he's a French Canadian with one of the hardest shots from the point and plays a physical game (something we lack). Age has a big factor, and Boucher isn't getting any younger so is value has dropped a lot.
He would probably retire here in Montreal, and at 35 years old, he probably has another 2-4 years left in the tank. He was a great specialist on the Power Play along with Zubov back in Dallas.
Boucher doesn't have the PP assets he used to. Heck, he only really had two decent seasons offensively. That leaves his only real asset listed by the OP as being French Canadian, which is complete nonsense, and a physical game. I don't think he's got the legs anymore to be an effective physical presence. He'd probably be replacing O'Byrne or Bouillon anyway, and they're both pretty physical as well.
I pretty much don't see any value in adding Boucher at all. Much rather have the 3rd.

since he's a French Canadian ...
If he's better than Brisebois (is he? I'm not even sure of that anymore), then I guess if we fail at all other attempts to get a better upgrade, then taking him for a pick or fringe body might be ok. But it sounds kind of like a Plan F option at this point.
