Hey Darkwing, it might be a smarter move if you explored some of the things that make CA so ez in A:M.
Alot of this stuff has been forgotten about with the advanced rigs that have beem made available to people, which are great for advanced animation...
but I think after reading your posts maybe you would benefit from just having minimal bones in the head/face.
for example, just have a head bone, bones for the eyes, 2pupil 2 eyeballs (4total) and a jaw bone.
then assign the control points appropriately and use poses to hold your control point and distortion box created standard lip shapes.
I used the basic tools for a couple jobs and it was a fairly ez process.
You can see a compressed sample of CA I did using just the above set up.
