The trick would be to get Cassini down near the rings and moving
parallel to them at nearly the same orbital velocity, so that the ring
particles won't pose as much of an impact threat due to their low
relative velocity.



That would be quite a trick, on the order of rendezvousing with one of
the F-ring shepherd moons.



That would be a ball to do also. A slow close in pass over the sunlit
side of the rings while staying above them by a hundred miles or so
would be great for picking up fine detail on their component's interactions.
