Well a little easier option would be an O2 trick box I bought them for my 97 Chev when I took out the cats..... You unclip the O2 sensor from the wiring harness(There was a connector on my truck) and plug this little black box into instead of the O2 and it would sent the appropriate signals to the computer. These worked great for me and I never had a code or check engine light again. I do not remember what they are called but I got them from a performance shop and they were around 80 Canadian Cedar Chips per unit. so I think in total it was a little under 200 bucks. I will see if I can find out what or who makes them and such details.

Logic for this was that it still would heat the sensor, but put it far enough back in the exhaust stream to keep it from getting a CEL. Results were mixed with this solution. Here's a pic of the arrestors and 2 links for more information...

this works great on the O2 sensors after the cat, I have never tried it on the upstream ones

upstream sensors do not require this due to the cats do not effect sensor 1

It all depends on the vehicle that you are working on, alot of the German car (05 and up) upstream sensors actually do look at the downstream sensors

I know with my old car, an 04, the front sensor is for the AFR and rear is cat efficency. One doesn't care about the other.

Is it worth the performance/mileage gains to eliminate the cats in the JK?

Is it worth the performance/mileage gains to eliminate the cats in the JK? I would say not enough ot cut up a good Y-Pipe with cats. I was looking in to this but to hollow them out and put it all back looking stock was not worth the Time or money. God luck on your 02 Eliminator.
