If you are running the Supersprint cats you might get the smog guy to let you pass on a visual, but that is a very slim chance. Your car has the pending rear O2 sensor codes because well..... it's looking the rear O2 signal to mimic a good catalytic converter.
You didn't say what O2 sensors you had hooked up and where, but I would think that if those cats are of a decent cell count (some way they measure the cats?) it might work. I would try installing O2 sensor bungs after your cats and installing the rear O2 sensors there, the tricky part then becomes finding connectors.
I dont know what kind of junkyards you have where your at but I was able to cut some connectors out of a car that had been in a crazy wreck and the engine harness was incomplete. One more thing, I would recommend using twisted pair wire wire to cut down on interference, you can find this in long lengths in most body wiring harnesses for the cars audio system.
