My thought also. Here are some links:

I would think that an engine out on takeoff would be about 100% fatal. Such
a huge difference in lift would cause an immediate wing over and spin.
It's essentially a "blown wing" or "powered lift" aircraft. *The only
way it would be even remotely safe is to link the props with a cross
shaft with Sprague clutches somewhat like the V-22 Osprey. *That way
if one engine failed, both props continue to be powered. *Even then it
could only be justified for special missions that needed the STOL
capability badly.
However, a single engine channel wing is possible.
Not exactly a Channel Wing, but this plane is a fully ducted wing
