On the other hand, there's no technical reason why one couldn't
hybridise the designs; the Orlyonok, for example, relied on blowing air
under the wings at least to break free of the water surface (I haven't
been able to confirm whether it was needed in cruise mode as well),
which is a hovercraft characteristic much more than an aircraft one.

What I'm suggesting is that the designs are in a continuum, and if one
wanted to build a hovercraft with WIGE-like characteristics it would
perhaps not be the huge engineering compromise that, say, a
hovercraft/conventional aircraft would be.
