I think a concern equal to the heat is that SMBC is not a great consistency to be out in the elements. Since it retains an 'uncrusted' surface, any little gnat or leaf (or heaven forbid a gust of dust) is going to stick to the cake. Under fondant, it will be safe. But I think that SMBC is way too vulnerable for outdoor elements.
