i actually already thought of doing that with the servos, like for the fingers and the head, i have a little robot in the garage, the robosapiens and i guess i could take the servos out of that and put them in the rancor once i am done with everything, i am still thinking of how the inner structure will be, i would like the joints to be in a certain way that they can be locked to put the figure in any position,i will also make some resin casts if the molds come out so that i will have the resin one and the puppet, tomorrow i will take that robot out of the garage and take it a part to see a little bit how it works and how i could use the servos in the rancor, they would be very usefull for the fingers and the head, i will cast the hands and the head separatelly from the rest of the body because indeed they are the two parts wich will have more complex components in them.
