Sounds doable... once you get the rotations nailed down setting up the parameters is as easy as

Create New Master

Start Teaching

Set master dial to 1

Set desired rotation to full value

Set master to 0

Set rotation to least value

Stop Teaching

Set limits to min/max value of desired rotation.

Let me know if you're stumped by something.

...as an aside I would avoid high valence vertex arrangements (poles) if possible. On the ear part for instance. They subdivide, morph, and render terribly. If you need a spherical area try gradual insets or extrusions and circularize/tighten to taste.
