Hi 420Dom,
I, honestly, do not see in the photos what you are calling bananas. I had some 'nanners' on two of my plants during the last grow (I suspect stress from light leaks). I carefully removed the 'nanners' for a few days, then they got to be too fast for me to remove, and like your plants, very close to harvest so I left them alone and decided to take my losses, as they were. The majority of the buds did not turn up with seeds, although, I did get about 100 seeds total out of 7.25 oz. of bud. There were also many small (the size of a grain of salt) immature seeds, but they were of little consequence. I plan to try to germinate some of the hermied seeds to see if or what they will produce. I read an article that stated that the hermied plants could produce 'feminized' seeds. I plan to try them on my next grow.
I was expecting the worst when I first found the 'nanners' on my plants, but that fear never fulfilled its self. My best advice is not to worry too much about it because, even with a few seeds, it will still be good!
