Depends what you mean by "good."
Do you mean "will it make me sick?" No. The alcohol, PH, hops, and simple fact that yeast have already eaten almost anything with caloric value keep anything poisonous from growing in your beer.
Do you mean "will it taste good?" For a hefe, you're probably OK, as long as your caps sealed well, and you've kept them in a cool, dark place. Oxygen, light, and heat will wreck your beer. Hop flavor will fade a lot over six months, even in well-stored beer, but in the style you're talking about, the hops probably weren't a big player to start with.
