I second noobinsf's suggestion of a different stem, and take it one step further.
What about an adjustable stem - a decent one, like a Ritchey - that's considerably stiffer than the average (poorly built) adjustable stem?
I put one on my wife's Madone, and that last cm of adjustment made a world of difference for her.
Even if you didn't want to keep the adjustable stem permanently, it might help dial in the exact rise / reach you need. Then you can get a non-adjustable stem in that dimension.
