You might be able to get the effect of sweeping a 3D shape around an axis of revolution by using the projection() module to convert the 3D shape to 2D, then using rotate_extrude() to perform the 2D profile. Whether you can find the right cut plane for the projection, in order to get the effect you want, will depend on the details of the 3D shape.
