Thanks for this experiment.  I was lucky enough not to bump into such
a weird situation and it had never occurred to me that the underlying
block size would "show through" an LV.

[ A quick look at Wikipedia suggests that a GPT partition table won't
  help because that also uses "block" addresses (LBA).  ]

Do you need a partition table?
What happens if you use diskimages that contain directly a filesystem
without going through the trouble of using a partition table?
Does `ext4` also get tripped by the different underlying block size?
