I have a hard time swallowing the idea 1 arm vs. 2 legs, hips and core strength to "scoop" them up. Why wouldn't you just block the hip with your left hand and go north/south and completely avoid having to deal with the strongest part of the body to finish the Kimura? Seems like a huge battle if your opponent fights the "scoop", especially if they are your size or larger.
Also just as a technicality that is not Twister Side Control. TSC requires your ass/hips up on the chest, not the floor, with pressure on his jaw, with your left leg up for base and balance.
