Tacking TJ caps on the front of YJ fenders and closing off the grill panel turn signal holes shouldn't be too hard for a journeyman body tech. Most bodymen could do it and make it look stock.
If you look at customized cars, there are plenty of even more extreme modifications that look like they were done in the factory.
Sometimes a person does something for no other reason than to have something a bit different.
That's a good idea to do if a guy is running a winch on a YJ.
