Don't do it, man. Just don't do it. Don't foul up your beer with orange juice.
And, I agree with Iordz. That recipe is more for a high gravity witbier, not a saison, although I do not know what you are going to do with your hops, there. Typically, a saison is a fairly simple recipe, often without spices (but certainly not always). Hop flavor and aroma is fairly restrained, but it can be complex. You need enough bitterness to keep your final beer dry, but you really do not need any more than that. Yeast really is the star of the show ina saison, and most of the beer's character should come from fermentation products. Any other addition should be there to support the fermentation character in the background only.
It is your beer, so brew what you want. If you want a saison, though, you need to rework your recipe. If you want a high gravity wit, you're off to a good start.
