Here's my prediction for this idea and I have seen it utilised many times before.

It will succeed for a while and it will do do as long as fresh new people with matching ideas continue to move through. But, what will happen in a few years? There will be solid clique with a strangle hold on innovation of progress and new fresh people will be shunted tone side and used if valuable or ignored and rejected. The entire structure will collapse on to itself amidst great recriminations and drama.

Would this happen with a men's group? Of course it could and has over the years, but with less regularity. Why less often? Because many successful men are dorks and social misfits and other men are used it and expect it and plan accordingly. There is none of this "magic" or "bonding" that is supposed to happen in women's groups. Men fully expect to be screwed over and behave accordingly. 

The major problem is goals. Men strive to win or succeed. Women strive to operate as a cohesive loving unit.
