Welding, Repair, or Patch Catalytic Converter Crack

I got rear ended and the exhaust pipe was mashed forward causing the crack in my Catalytic converter's weld. Or perhaps, it just worsened the crack if it was too small to notice before. The crack does NOT go all the way around. I have not had a CEL appear and have had the crack for 1k+ miles.

To me, the crack appears to be in a spot that could be welded. I am looking for suggestions from folks with exhaust work experience, what is the most sensible approach to fixing this crack? Obviously, the goal is to avoid replacing the otherwise healthy cat. Thanks:enter image description here

I am thinking, at minimum, a few spot welds would stick. I could then use a patching material of some sort? Ideas?
