I'm not a math major, but in my experience, it's pretty much impossible to get your GAA below your opponents. Bringing it down from 2.3 to 1.6 after 4gp would pretty much mean 2 SO (I think). The SV% might be a bit more doable but unlikely.
I think, as it stands right now, you have to go after F stats. And even though I don't think many/any goalies are playing better than Emery right now, I'd go after a forward. Of course, this all hinges on whether your opponent's goalie stats remain static.
