Is possible to use foreign wondercards in a NA generation V game?

[Gamer2408]

Hi, I want to try inject some events, but first I want to know if I can inject wondercard from others regions like Japan?

P.D; to be sure if I'm doing this right, I open pkhex with the gen V SAV, later I click over the mystery gift button and I import the wondercard that I want, save the changes and everything should work fine, right?
