Sure, but the range is limited to what you can switch. I would want to do it with SVG and bitmap and every other kind of thing.
I probably didn't understand what you said, but you can change models and keep motions, just go to "compose mode" and on "Content manager" change the actor, when you back to "Stage mode" it will be with other actor and keeping the motion. with props you cand use "Sprite editor" tab.
