Possible, but not practical.,, it would involved lots of deep magic of
modifying the hotplug scripts....

mdadm is not getting confused by the changing drive letters.  By
default, mdadm scans all devices to find members of it's raid array,,
but it may need a bit of convincing to start a degraded array if one of
the drives is simply missing out of the blue..

try mdadm assemble -R /dev/md0
