From a practical matter, they will just hook up a tailpipe sniffer and make sure that your emissions are within specs for 1991. (It might be a different story if your Jeep was 1996 and later with OBD2)
I did a swap in my 1995, and the inspection station has never even opened the hood to check anything - other states have much more vigorous exams.
In any case, I don't really see how you would benefit from leaving any of the emissions components off after your swap - put it all back in there.
