Stroke following the boundary of an object when rigging

Hi everyone,

I am relatively new to After Effects. I was planning to do some rigging with Duik. I have all the different limbs to be animated, each with its own stroke. I would like only the outermost stroke of the overall body to be visible and adjustable at every movement of the body. To clarify: let's say I have a glove with white rounded rectangles with black strokes as fingers. I don't want the strokes of all the individual rectangles to be visible, but only one stroke on the outer profile of the whole glove. I can do that on Illustrator, but when I animate it with Duik that outer stroke would change because of the movement of the glove, since the overlap between the fingers would change. 

So, is there a trick to make the outer stroke follow the glove when rigging?
