Touche.
As a hypothetical scenario, If it is symetrical from axial loading, spread them symetrically into existing footing. Make sure you give more than 3 inch cover on the side dowels into existing footing side,and avoid existing reinforcement.
Also you need to clean the exposed concrete on the sides where the new concrete will be cast against, and coat it with a binder.
Now comes the trick part. What will you do about bending reinforcement? Hence back to my basic question. This is a classroom discussion.
