I had a friend years ago who had a similar problem. This was in a state with no emission testing at the time. Her cat also failed to the point that the engine wouldn't run properly. The cat was basically plugged and wouldn't let the exhaust through. So a mechanic told her he could poke holes with a screw driver through the guts of the converter to allow the exhausts a pathway through. This was illegal and allowed the exhausts to completely pass through the converter without being treated. Bad for the environment, but she got a few more years out of that car.
I doubt you could find a mechanic willing to do that for you, and it would only buy you enough time to make it to your next emissions test, where they might prosecute you when they see what you've done, but it's probably not all that hard to do yourself. Understand that I'm not recommending this, just relaying a story.
