Though there has been at least one NJA captain who has taken an SIC seat at NJI. It is an option if you aren't senior enough to hold a G-IV captain slot and you don't mind the pay cut. It is rare and it isn't a requirement, but it is a choice you can make. I believe there is at least one BBJ SIC who was a captain before and took the lower pay for a different kind of flying. I believe NJI has somewhere around 45 big Gs and NJA has 2 BBJs and maybe 5 2000EZs that qualify for the higher FO pay. Overall it is a small fraction of the fleet. Most of the big airplanes are now going to NJE- they already have more G-Vs and 550s than NJI and they are getting something like 35 7Xs and they just announced an order for 20 or 30 2000LXs. I believe NJA is going to get some 2000 LXs, but not the same numbers as NJE. I wish we were getting some more here, but that just isn't the case.
