Yikes, that looks scary. We also looked at a really cheap Kia that ran in Lemons in the early 201X's, apparently twice, but we saw sketchy cage work comparable to this. I doubt what we saw, or this, was ever legal but I can't help but wonder if inspectors were looser back then. Surprised people were comfortable with racing in these cages, even if they did pass tech.
Hows the rest of the cage, are the welds OK? If everything else looks okay, I would consider pulling it down and trying to notch and meet as they should be. You wouldn't be able to get a proper tube bender in there, but you might be able to fit a pipe bender. I've bent cage tubing in a pipe bender by tac welding the tube at the kink point to the mandrel. Gives nice kink-free bends if you do this trick. If you ask John, any of the inspectors, or a good cage builder, they'd advise to start over.
