No and No.

The cone sweep is only for prism. It makes the edges converge toward a
point. Good to create a pyramid.
In a sphere_sweep, each point require a radius. That radius can be
negative causing a pinch point in the sweep. OTH, each component can
only be perfectly spherical, NO scalling of any kind and NO other transform.
For a scroll, one option would be to use a sphere_sweep with components
having a very small radius, then, to apply very uneven scalling.
Something like using a radius on 0.001 unit and all points in the same
plane, then scalling by something like <1,1, 300000>.
If you only give 2D coordinates, the Z coordinate should default to zero.
