It's ok.
Chances are, it's just going to transpose into an exchange with an early c4. Which is regarded as a legit way to play against the French, but ain't exactly critical. You'll probably get an IQP structure, and have to play that way instead of in typical "French" fashion. If that's your bowl of wax, you could do worse.
But then, you can do the same with a more typical 2.d4 just the same.
is 1.e4 1.e6 and then 2.c4 any good for white if he wants to avoid french structures?
