I think you still have the same problem, just more uniformly distributed. Imagine a dome shaped panel. No matter what the orientation relative to the sun, the panels are equally facing it. But even still, any particular point in the dome has an orientation and it's only ideal while it's ideal. The point facing east is ideal for sunrise but is useless at sundown. You get as much uniformity as the sun and clouds give you, but you're equally wasting the same amount of panel face at any given time.
Not sure if it's feasible, technically.
