Change physics body shape during code execution?

I created a physics body with a sprite sheet and a custom rectangular shape. I would like to make the shape smaller by 1/2. Is this possible? I tried the scale property but it only scales down the visible image (sprite) and it won't let me re-assign the shape coordinates.

The easiest way of actually doing this is removing the physical body and re-adding it. Is that an option here? (This is because of box2d limitations.)
