I cannot speak to what yeast AnBev uses.
I assumed this beer was created to compete with Molson/Coors' Blue Moon. From what I remember they are very similar but have no real authentic belgian character which is why the masses enjoy it. I think Wyeast American Wheat may be a good idea even though that is not what is used. Also throw in some coriander and orange zest at the end of the boil.
I do an American Wehat with US05, coriander, orange zest and it works great. It is somewhat similar to Blue Moon and Shock Top but a little more crisp
