I don't really understand the problem. I was in an N for 1.5 years and it worked well. We had no problems with 2 hinges. I actually thought it was a really balanced situation and in some ways better than V. I'm stressing the words some ways, and this is of course just my experience. Obviously it all depends on the people involved but I just don't see how the N configuration and 2 hinges would be more stressful than a V. Would you like to ask a bit more specific questions or give examples of situations where you think it would be difficult/stressful?
