I don't know if the bezels can be swapped but if I understand the reason for your question then whether or not they can be swapped doesn't matter. The 05/06 controls do have an AC on/off switch but it only works in certain modes; for example even if the AC switch is off the AC compressor runs when the defrost mode is selected in order to dry out the air being circulated. I suspect the 04 is similar.
If you want to turn the AC compressor on/off in all modes you have to install a manual AC compressor cutout switch like kapalczynski did or mess with the circuits on the switch itself somewhat like this post
