You'd need to add a crane tender with a cab to house the AC Commander, there's no way you'd fit it into the cab of the Burro Crane. As for cab rotation and raising and lowering the hook, that "might" be possible using something like model airplane servos to move the mechanical levers to trigger those functions. I haven't looked inside of one of those for a very long time to see what space is available.
It would probably be easier if you converted it to a can motor (takes much less space) and then added the required electronics and mechanical servo systems. Even so, it would be a fairly complicated project to do more than just run it up and down the rails.
Let's say that it's not going to be a project for the faint of heart.
