I've done this to my HH Hyperlight and it is holding up fine. I did it so that in the winter I could use my sleeping bag like a peapod without the netting interfering. Since the netting is cut smaller than the ripstop, I don't turn my hammock over when i sleep in it this way. I just sleep on top of the netting. It's held up well this way for the past two winters.
