Sorry to bump, but I'm interested in hearing if the developers have any ideas about the JPEG2000 file size and quality discrepancies.
In the meantime, I've switched my script to regular JPEG for more consistent results.

Have you tried using
-background black -alpha Background before saving to jpg2000?
Does this make s difference to your final file size? It should not change the image in any visible way, just assigned the color behind fully-transparent pixels. It would hopefully mae the compression just that much better.

No, adding that option results in no difference to the final file size.
