Finished up a set of preview images for this encounter:

https://pirlwww.lpl.arizona.edu/~perry/Juno/pj55.htm

This uses the PJ53 images as a template for image timing, so images every 3 minutes ±10 minutes of C/A then wider spacing outside of that. Juno is oriented so that is off nadir so it does a better job of keeping Io in the middle of the JunoCam FOV (and JIRAM centered on Io as well, which is great as the drift near C/A can lead to only a few images being taken making summed images have poorer quality).

The original trajectory would have flown through the radiation belts much more often. How much instruments would have degraded by now is hard to say (but it's definitely serendipitous!)

But it would have taken data much more frequently near Jupiter, so even though the mission has been a lot longer, the amount of science data is more or less the same. Satellite encounters notwithstanding.
