Non-rocker ankles suck. Rocker ankles are much better for stability and the only thing that allows a stance other than straight up and down without looking stupid. Feet should always be flat to the surface.

as a concept I agree with you. in execution, I have yet to see rockers that were superior and that didn't "self-rock" their way out of relevancy.

What about a ball jointed ankle. Similar to the current neck joint.
Pretty similar range of motion as a human ankle.
It would allow for tilt and upward/downward motion, and would still retain the inward/outward swivel.

AND potentially be more stable than most rockers available today. color me intrigued.

Although - and maybe bossfight is already do this - a rocker ankle the pegs not just into the foot (where the rock comes from), but also into the leg (to allow the swivel) could theoretically work - if the joint was tight enough to support the weight. That is perhaps just a different way of describing your idea?

Pretty much.
Right now rockers are basically a ball in to the foot, attached to a hinge at the ankle. If it were a double ball, like the current neck articulation, it would be like you are describing.

It could even be a ball at the foot and a post in to the leg, that is the same as the posts already used. It would have the same basic effect, and be compatible with the already existing legs.

Not sure if it would be beneficial or not but the ball, in to the foot, could have small nubs on it, similar to those on the MU hip balls, to help 'grab' the softer foot plastic.

Here are a couple (very) quick diagrams I threw together.

The first is the simple ball joint we were talking about. The ball on the bottom plugs in to the foot, post on top plugs in to the leg.

The second is my new favorite idea for H.A.C.K.S. ankle articulation.
It's a bit more complex, but not too much though. I'd imagine the two halves of the ankle would just snap together. The post going in to the foot would be like the current rocker ankle method, except the two piece ankle would provide the up / down articulation and the post in to the leg would add rotation.
These would be VERY similar to Revoltech joints (which rock, hard).

Both would add rocker ankles while retaining the rotation and elevation. As a bonus they would both be compatible with the male legs BFS have already made.
Revoltech type ankle joints NEED to happen.
