Hi!
Since Cassini is in an elliptical orbit around Saturn,
I was wondering...

(1) Is it possible for the Cassini spacecraft to receive gravitational assists
from its moons to attain escape-velocity eventually, if that were deliberately planned and desired?

(2) If Cassini can be gravitionally-boosted by the moons of Saturn
to Saturnian escape-velocity, after the primary mission is over,
could ity receive additional gravitational-assists, from Saturn itself, to redirect it to (3) Uranus?...or (4) to that asteroid/comet nuclei, Chiron?
