ISTR that this does indeed happen in one of the stories.

Depends on the design, but generally the skirts are designed to keep
outside air away from the cushion as much as possible. I very much doubt
that compression under the leading edge will be significant compared
with compression from the main lift fan.
On the other hand, a vehicle could be _designed_ for this mode of
motion; googling for "ekranoplan" will show a lot of vehicles that were
quite specifically intended to operate over water.
