How could I turn the default unreal template character into a stick figure?

I was wondering what the steps would be to make a copy of the default character template, the white robot guy, and edit him in 3ds max or blender to be a stick figure, but be able to keep his animations.

I basically just want to make his head bigger and then make it a globe, and then just turn his torso, hips, arms, and legs into cylinders, but keep his hands the same, maybe bigger fingers.

Could anyone just type up a list of the steps I’d do, like “Import this file into blender, do this, export it” and whatever other steps needed to maybe reconfigure the animations for the new skin.
