To Echo the above. Cape Air still flies Cessna 402 twins and have for many years. They too purchased any 402 out there, do all their MX and I understand even make some parts. Good safety record. I've flown them a few times and its a hoot going into Boston in a little twin. The have got it worked out with ATC.
Feels like you are going to get around the big boys on the ground by sneaking under them.
