Re: Kubi Nage???
I've seen something vaguely similar, called kubi-ate kokyunage. So a neck-striking throw. E.g., from yokomenchi, nage steps inside uke's strike radius and counterstrikes the neck to throw. No head-twisting, though. I remember the oddest thing was that nage's rotation isn't the way you'd expect...like. Let's see. From gyaku hanmi (left foot forward), nage would step in with the left foot, rotate clockwise on the balls of their feet, and then strike with the right hand.
(My recollection is a bit fuzzy.)
