How about a double flyby of Saturn and Jupiter? Saturn first, then
jupiter for the plane change and final kick? Adds a bunch of time,
but they're both on the same side of the solar system now, though
maybe not for long enough to matter.
Also, what about the antenna needed to get data back from the probe to
us, without tying up the 70m DSN dishes? Or did Oumuamua go north so
we have two 70m dishes available?
Or will laser comms be sufficient at that range?
