Oh, I actually flipped around "min" and "max" when reading that. What you mention is actually two separate questions - firstly, balancing vertical vs horizontal will have to be done in some way anyways. Maybe use Manhattan distance to normalize? Secondly, I'd only want to cap if we find a definite need for it. The incoming intensities are going to be naturally capped at 1.0, so there's a natural upper bound for light intensity anyway.
For restoring shiny materials, we could re-calculate the normal vector as (right-left, top-bottom) and intensity as the sum of dot products with that (hm, expensive?). This would be a completely separate shading path that adds a highlight. This would be the "proper" way of doing reflection anyway, because the angles you consider are different.
