user3270: My style favors aggressive, complicated openings. I have constructed a suitable repertoire with White beginning with 1. d4 with one exception. I have so far been unable to find a satisfactory response to 
[fen ""]
1. d4 d5 2. c4 e6 3. Nc3 Nf6. 

I would prefer not to play the Exchange Variation because it is extremely popular among my regular opponents, but if it is the only option I would consider it. However, this would mean also finding something against the Alatortsev (3... Be7). 
Can anyone give me a good suggestion? I'm willing to go into less popular lines if they have been tested by a 2700+ at least once.
Edit: To be clear, I'm already set vs. the Slav/Semi-Slav. I'm purely concerned with situations where Black does not play c6 at some point.

user7465: I'm pretty sure I have seen strong grandmasters play a setup with Nf3, e3 and g4!?. You may want to look closer at this.

user924: Maybe the 5.Bf4 lines are a good fit. In the 5.Bg5 lines, black can often exchange bishops with the Lasker/Capablance maneuver, involving an early ...Ne4 or ...Nd5 forcing the bishop exchange, and it is hard to get aggressive play against that. 5.Bf4 avoids that, with the drawback that there is less pressure on d5, allowing ...c5 by black. Usually white takes the pawn.
There's an all star list of top players who have used it -- Kasparov, Topalov, Ivanchuk, Kramnik, Gelfand, Korchnoi, et cetera.
I should probably add an example game here but I don't know one from the top of my head and I don't have much time...
A recent book that advocates this line is Burgess' "A Cunning Repertoire for White", which is a generic 1.d4 opening repertoire book.
