Agreed, there will be enough yeast to carbonate...But. I believe that something magical happens to Belgian Style beer during bottle conditioning. Since the first time I added more yeast at bottling, I will not bottle without it. Belgian breweries believe this as well and add 1 to 3 million cells per ml at bottling (the latter is 60 billion cells for 5 gallons!).
Try this if you can and report back: After bottling half your beer without yeast, add 0.5 to 1 gram of Bell Saison dry yeast (rehydrate if possible). If you don't have a good scale, 0.25 to 0.5 tsp will get you in the ballpark. The beer without yeast will carbonate but the beer with added yeast will have different flavor profile that I bet you will enjoy.
