I don't see why one would assume that the pit would grow up to "savage" the basset. I once fostered a pit, he was a very sweet dog and was never a problem with any of the 15 bassets I had at the time. The worst problem I had with him was that he wagged his tail so hard he kept injuring it. I met him again as a senior and he was just as nice.
FWIW, lots of terriers at the shows are scrappy - scotties are the worst in my experience.
