Nope, it won't work. It still has the same problem of
sampling the current (and nothing else) at only one
point. The two pickup coils are reading exactly the
same current just with opposite phase. You still don't
have any means of separating the forward component from
the reflected component. Your toroid is NOT a directional
coupler - it is a current transducer.
