MOPAR cars it's easy and almost recommended to have a second ECU instead of reprogramming. I'm not sure about GM vehicles. Anything is possible and doable with enough time, money, and effort. For me it was just easier to run cats and not worry about the hassle. I'm sure you can find a shade tree mechanic that would clear you for a case of beer or an extra $20 and skip the extra steps.
