Even a static mesh can be used as replacement: the mesh will be instantiated with the soft body settings of the object. The position and orientation of the soft body is preserved after the replacement. Known limitation: the velocity of the soft body is reset aftet the replacement. This is because soft body don't have a well defined velocity.
