To solve the problem with the shot leg servo I replaced the electronics of the servo with that of another one and successfully installed a ball bearing in each leg.

They now work as well as can be expected given the servos low power and resolution, but its better than not moving at all. Still, I feel like I have shifted the role of the "worst working part" to the arms, as they still shudder around quite a bit as they move. So I tried to calm them down a bit by putting some pauses for them into the animation. The result however does not look much better as they now appear to be moving too little.
Overall however I am very happy with having achieved motor function in this nice toy and I am looking forward to be working very closely with him.. in private.
In general this experience has teached me that it is just not economical for me to use Servos in large scale models, at least not in major leverage situations like neck, arms and legs. I may just have to start working with pneumatics or rather a cable pull system with step motors. High Power servos of the Tier I would need go well into the 3 digits and the amperage needed just to hold a paper head up is almost creepy.
