I like the Cassini Mercury crash option, even if unlikely.

I don't understand why a Saturn impact trajectory would neccessarilly have to go through the rings. Giving it just the slightest inclination at the last Titan encounter would bring the spacecraft - er, "safely" may not be the most appropriate word here given the end result - above or below the rings and into Saturn's atmosphere in that same N or S hemisphere.

Actually, I like the idea of putting into a more distant orbit around Saturn. That would maximize the science until the very end, rather than putting Cassini on a long interplanetary cruise during which it's remote sensing capabilities would be wasted except for a rare flyby (by which time the spacecraft might be inoperable, anyway).
