Maybe you are to far in your process, but what if you set the thigh joints like real thigh joints?
A real thigh bone is shaped like an L attached to the pelvis bone.
How would it work if you align your thigh joints like That L too, and making the longer bone a stiff child of the shorter bone? 
That means a Y rotation of the thigh parent bone makes the leg bend,
a Z rotation of the thigh parent bone makes the leg move to the side,
a X rotation of the thigh parent bone makes the leg twist.
Just an idea, that someone might be curious to explore.

Just my opinion here but I think that AmbientShade is looking to create a figure that would be most widely accepted and supported. Generally it seems that figures with novel "avant garde" rigs don't fare well for wide acceptance, not to mention that such a leg set up that you describe might not behave as expected in terms of IK... if at all. I've seen it before. Worst case scenario is that Poser IK wouldn't work properly. A figure without working IK for the legs is doomed to the dustbin of marginalization. Ideally you'd want a figure that conforms to traditional Poser standards but shines in features that are more conducive to usability.

Just my opinion... I may be wrong.
