So just to make sure I understand you want to use Demon Boots of Healing on your whm, but have them look like the Emperor's New Shoes and use Daystar boots on SCH and have them look like World of Darkness shoes? Theoretically you just need to remove the glamour from the WoD boots glamour them on to the Daystar and then re-glamour the WoD boots. This won't work, however, as you can't glamour a higher ilvl item onto a lower one.
