Easy, maybe, but not great. I play the two knights Caro-Kahn (1.e4 c6 2.Nf3 d5 3.Nc3), because besides the fact Black often transposes in a KID with color reversed and two more tempi for me (by 3...d4 (?) 4.Nd2 c5), White takes no risk, but I never got a lot out of the opening either.
So with the French, where ...e6 is more of a developing move than ...c6 (because the Bf8 becomes free), I don't think this could lead to great prospects. It's a good try if you don't want to learn any lines, but do not hope to refute the French.
This is called a 2 knights french
1.e4 1...e6 2.Nf3 2...d5 3. Nc3
