against paradox line white should just develop normally, e4 c6 d4 e6 Nc3 d5 Nf3. even if the game goes 3 Nf3 d5 e5 you're a tempo down in the french advance
Honestly, I would probably play d6 first, since this what one should do if someone pushes their e pawn too soon in the French. It is cramped but, it is playable...
