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.

Seems to me that the signal would have a pretty difficult time penetrating
the ionosphere at HF frequencies.There are of course complications to that
answer, such as MUF and incident angle, but in general if the ionosphere
acts to reflect earth originated signals, it will do the same to space
originated signals.
