Possibly. But I think the stars that do the polar jets are not necessarily
the kind off star you want to put at the center of your shell. Then
again, there might be some solution involving either stellar engineering
or some sort of inner shroud to redirect some portion of the radiation to
the poles. (Of course, this would again cause excess heating problems.)
