I think that you could have your hands full with that combination myself. One of my friends had two BR's which I believe have now been re-homed. They were lovely dogs and great characters though. You do have to be careful and check the lines. I've had other friends with SCWT's who have been great but then a bit funny with other breeds.
I'm sure that someone will be along who can help you more and knows more about the two breeds in question.
