physics : blow sheets of paper with wind?

I need to create an animated shot where sheets of paper would be blown away by some (directional) wind, like you would do with leaves :

I'm hesitating between animating it by hand (using curve modifiers on my sheets) or with physics. It should be quite realistic.

Would you consider doing it with physics, or is it just too much work ?If yes, how would you do it ?

Thanks !
