No offense, but I think Efren, or for that matter, a lot of todays pros, would do just what you said, shoot the shot with bottom left, and just draw it right back.
Nothing "virtually impossible" about this shot. Line up on the shot as if shooting a normal draw stroke, move your bridge hand a little to the left and you'll be applying low left english, then move your aim to the right slightly, depending on how much your cue deflects, and how smooth your stroke is. If it is smooth, then the english will "take" soon after the stroke.
No doubt, you have to have a smooth stroke to even think about drawing back, but that's what practice is for. The problem intermediate players have with shots requiring this kind of stroke is that:
1. They hit the shot too hard, not allowing the cue ball to curve back after deflection
and
2. They move too far off center ball when applying the inside english. Only enough inside need be applied to compensate for your cue's deflection.
