I personally would try to avoid such a change (really IMHO), especially if 
it's "only":

_one_ user. Could Thunderbird or another IMAP client be an option for this 
single user? And perhaps Apple can tell some details when their Mail client 
will be standards-compliant?

Besides that: changing the hierarchy separator is generally possible. But 
you schould try and check that with a test system to prevent problems with 
your productive environment and all the other users.
