Will, Just another opinion here: I would not attempt to alter the position of the hand without visual information at the ready. If you feel his hand has too much dominance, (problems inherent in photographs), you can diminish it with desaturated color, soft edges, and slightly diminished value. Her hand, close in, will move forward with sharper edges and more saturated color.

Such impact is well demonstrated by Daniel Greene's auctioneer series. (Current in my mind this week.) When I get a moment I'll try to locate an image online.
