Here's what I did (on x86 Linux):

$ tar -xf Ara2012D.txz
$ cd Ara2012D
$ xz -dc disk.ima.xz | dd conv=swab skip=1 | cp --sparse=always /dev/stdin partition.ext4
$ e2fsck -f partition.ext4
$ resize2fs partition.ext4 512M
$ truncate -s 512M partition.ext4
$ e2fsck -f partition.ext4

This shrinks the filesystem so that it may be copied to a physical disk 
from an m68k machine. I plan to expand the filesystem again to fill the 
larger partition. It contains /sbin/resize2fs, so booting into it and 
doing an online resize should work.

In theory, it should be possible to do that with MacOS. E.g. copy 
partition.ext4 and a kernel binary over FTP, then block-copy 
partition.ext4 to a local empty partition using SUntar, then boot into it 
with Penguin...
