You could, but traffic returning to the client would appear to come back from the ip on the dsl line, and would be rejected by the tcp stack on the remote host. Here's an easier solution. Change the TTL in your dns to like 15 minutes well in advance of the move. When you move the box over, change your dns at the same time. That way it will minimize the amount of time it takes for your dns to propagate (less than 15 minutes).
