In my experience riders who try to adjust fit merely by raising the handlebars end up unsatisfied. You do not say what else you have done, but it's important to first address seat height and fore-aft position and then seat-to-handlebar distance before height. Otherwise you are chainging weight distribution more than you are changing reach.

I would also point out that a fork with longer crown to dropout distance will reduce the head and seat tube frame angles, move weight distribution toward the rear, and increase trail.
