The point I was trying to make by reference to a "canard" layout - small forward lifting surface and larger rear lifting surface - is that such a configuration is stable, despite the cg being well aft of the cp of the forward lifting surface.
Stability is concerned solely with the position of the cg relative to the neutral point of the whole configuration. If the aircraft is so configured that the neutral point is quite a distance aft of the cp of the forward lifting surface, then you can put the cg between the cp and the neutral point, and the rear surface will provide lift, while the aircraft remains stable.
