Morph on item equip

Added frostmourne item and would like to let a player morph into the Lich King when he equips the sword?
Is this possible by edit the db only?

Not sure if this spell works, but check http://www.wowhead.com/spell=43811

You could try applying this aura when equiping the item.

Use the spell_linked_spell table: chocochaos’s spell (43811) with the Frostmourne spell (43827, item_template.spell1 of Frostmourne item)
