Sutemi-waza = sacrifice throw
Some of those could do it, we have one called shizumi-othoshi, but it's not a "sweep" in any judo sense of the term, a gari movement, which is generally referred to as a sweep or reap, sort of brushes the persons foot/feet along the floor and out from under them. What I'm envisioning is uke being impeded by nage's body and falling over them with nage standing up in the middle and Wallah! Big toss.
That what you mean?
