No, the structure looks like this:
/vservers/shadow/myVserver/usr (linked contents)
All of the /vservers/shadow/* directories are hard linked replicas of
each other, using immutable file contents flags.

Each approach has its own drawbacks and limitations I guess. I assume
that unionfs is a union mount - mounting a filesystem on top of another
one so that you can "see through" to the contents of the filesystem
underneath, but new files get created on the filesystem "on top".
But what about removing files? How does unionfs handle that? ie, if
there is a file present on the "master", can you remove it from the
union mounted version? Or only replace it?
