Wouldn't that provide a better coverage with less fading compared to
traditional approach? Or is it that shortwave needs ionosphere to
work at all? Thanks.

Aside from the propagation issues, the usual antenna for satellite work is
highly directional. Antenna size is proportional to wavelength and SW
wavelengths are a hundred times or so bigger than the usual satellite
wavelength.
