I wouldn't use such a combo in sparring, as sparring is completely different than scenario replication. In a scenario the person who is the assailant attacks you with whatever, punch, tackle, knife assault, and you just react.
If you want to see it performed alive with resisting opponents, check out the videos of Richard Dimitri of Senshido.
