Thanks for the additional info. It looks to me like that process should
be modified for shrinking to:

1. Resize filesystems
2. copy to outdisk (w/o size change)
3. Edit partition to match resized filesystems
4. Truncate outdisk

This should work for msdos labeled disks. For GPT, I am not sure what
parted would do when you truncate it (which will chop off the duplicate
GPT table).
