You could run the 2004 GTO drive by cable OS in a 6243 PCM with minimal changes to your factory wiring, but you'd lose your dual fan speeds
I don't know of any 2004 OS's that would allow you to keep dual fans speeds, without running the BCM that goes with it
I don't see any advantage of switching to the newer PCM, since you already are running a 411
