but again, with frictiontype gearboxes, more can go wrong. i think its more worth lookinginto having the cone/himisphere as the final part rather than within somewhere.
i have a feeling something of the like has been patented tho. i have seen tilt wheel rc toys.... not sure if variable speed/torque was the point of those tho..
but if not, twould be sweet.

What's further interesting about using hemispheres as wheels is that you can maintain constant driving power to them. You can drive all four "wheels" with a single gearbox. You do not even need to vary the power output to vary its speed.

if you drive all 4 wheels with the same gearbox how can you turn? or are you saying about the angleing?
a leadscrew...hmm... or wormgear....or....
