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

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)
