No, because to do a full restore of the 0.20 database backup, you'll
have to drop the existing 0.22-fixes database.  Once you drop that
database, you can't start mythtv-setup or mythbackend until you've
restored the 0.20 database backup /and/ done the appropriate hostname
changes.

You'll have to stop them (all MythTV apps on all hosts--all
mythfrontend, mythbackend, mythtv-setup processes) to drop the
database.  Once you drop/restore the old 0.20 database backup, you've
"reset" the clock on the "before starting..."  See
http://www.mythtv.org/wiki/Database_Backup_and_Restore#Database_Restore
for information about dropping/restoring the database.

But isn't it it possible to do a backup of the 0.22-fixes database before dropping it, do the steps you have described and then restore it again?
