If you could do it for Parise/Kopitar I would do it.
Giroux + Parise is the best of what you posted, but I'd have a hard time doing that.
Just looking at Points...
Malkin - 110 pts
Brown - 60 pts
Total - 170 pts
Giroux - 90 pts
Parise - 75 pts
Hmmmm... maybe I would do it. That opens up your last keeper slots for when you want to call up one of your prospects. Tough call.. could go either way.
