Doesn't make it a hovercraft-ekranoplan hybrid, sorry. Without a plenum 
chamber there's no trace of any hovercraft heritage.

Almost certainly not - just like normal flying boats, WIGEs need far
power during take-off than during flight.

IMO it is about as much a "hovercraft" characteristic as booster rockets

for carrier-launched aircraft are, or the underwing exhausts on a 
Harrier... or the engines of just about every flying boat in history :-/

And what I'm suggesting is that they aren't! Sure, you can build a
hover/WIGE in the same way as you can build a hybrid boat/car (not just
amphibious car, but an amphibious car with boat-shaped hull/boat with
wheels) or van/aircraft, or why not a van/spaceship like Lone Star's
Winnebago... but all these craft have two *separate* sets of propulsion 
equipment; they're not sliding on some sort of "continuum" between their

different propulsion types.
