"IF" it takes 2 hours to get to NBO from wilson (should be quicker, but never know with their traffic, could be longer, but I feel 2 hours is safe), that gets you to NBO 2 hours before flight time. If you are comfortable with that, go for it. I probably would, but it's tight. One more hour would feel a lot more comfortable. But most likely the next flight options is several hours earlier....
