Standing on a balcony behind a railing, or riding in an SUV, his double could be 5'9" and standing or sitting on a prop.

Personally, I think we've already seen one of his doubles, with him wrapped in a cloth to cover all but his eyes standing behind the double alongside of Osama's #1 man who is short but with whom height can be manipulated better than the double's height. I would wager there are fifty suitable Saudis that could double, even with minor cosmetic surgery. The eyes are the key and the actual shape and folds of the ears.
