One thing that i would object to with the mixing or those 2 breeds is the coat they will have when they reach adulthood. As a groomer we have run into a lot of dogs crossed with one or the other, most crossed with schnauzers are really homley looking dogs(cute as pups), and sadly there are so many owners that are too judgmental and get rid of it. And wheatons have a high mantinace coat that matts really really easy and tight, even i would not own a wheaton or cross for that reason, and their personality is not one that most tolerate, from what i have seen and heard. Not saying that you wouldnt take care of it, but there are A LOT of ppl out there that wouldnt.
