That's understandable. Since it took literally everyone else getting hurt before we'd even put someone Baun's size in that role, that's why I don't see us planning to put the even smaller Hudson there.
Underhill has said several times that the team has indicated that they are now willing to sign/draft smaller/faster Edge guys now given the extensive use of three step drops and mobile QBs these days. He's mentioned that they do really like Dallas Turner despite his size. But, I'll believe it when I see it.
