IIRC (and I might not), Cassini's orbit will be back in the equatorial plane at this time (at least it should be if there's no change in inclination after the end of the primary mission). To me, this seems like a good opportunity to look for larger ring particles, the ones that are presumably plowing out the ringlets.
Actually it might be better for Cassini to be in an inclined orbit at the time of equinox. Larger ring particles would be more visible seen from above than from the side.
At the exact time of equinox they would appear as bright dots on the darkened ringplane.
And, in the days just before and after equinox, their shadows on the ringplane ought to be visible.
Besides that, IIRC, when you look at Saturn's rings edge-on what you are really seeing is the F ring. So at equinox the edge-on view might not be much different from what we normally see.
