Any Good Alternatives to Queen's Gambit for White for players 1600 and up?

I want to avoid playing Queen's gambit due to it being played way too often. Any good alternatives for white? This is mostly for ratings 1600 and up. I thought about Colle and London but they are rarely seen in master play. What are your opinions? 

d4 openings only 

E4?

The only purpose the opening serves is to get to a playable middle game.   

Nf3, they often transpose into d4 stuff. Normally it gets interesting, not always though.

I've never played it, but the Levitsky Attack looks like it might be interesting. It doesn't score as well in GM play as Queen's gambit, but it looks solid. If you learned it well I suspect you'd have a good chance to know it better than most opponents.

The one response that looks dangerous is f6. 

1.d4 d5 2.c4 may be played often, however, there is an absolute plethora of variatons, and this means you can still easily surprise your opponent by playing a line which isn't so mainstream. I recommend you stick to the queens gambit, and if inclined change the variations within it that you play.
