I would print one of the three (I think they all have qualities that make them worthy of a good print) that you believe most shows that good humor. My choice is number 1, though 3 is the most conventional. I would then suggest you work your magic on number 2, since she seems almost impish in that, and if I may say so, that fits your style. Give her both images. She may want to display or reproduce the straight shot for public consumption, she will either love the altered image or hate it, but give her a chance to do one or the other. It's not as if you were going to publish the altered image without her permission. She is receiving a gift from a talented and distinguished artist- she will most likely be grateful.
