You'd get a mix between the two, resembling a brown corn snake of some sort. I wouldn't do this, it's irresponsible in my opinion. The point of captive breeding is to keep genetic lines pure, not muddied with other genes. We do not need mutts. They aren't worth anything anyways if you are looking to sell them, and the offspring are not usually viable.
Called Beast corns. The pics I have seen look pretty cool. Just do a search for them and you will see some pics. Might be cool to see what you might get by mixing morphs around like people have done with the root beers and creamsicles.
