This all still works so i figured, why not other temp enchants. Using the same method of putting in some pve gear then swaping out to my pvp gear in the prep room I got these to work with myself and a partner:
Greater Ward of Shielding (Greater Ward of Shielding - Items - World of Warcraft)
Greater Rune of Warding (Greater Rune of Warding - Items - World of Warcraft)
The plus is even if you die, these temp enchants stay on your armor/shield as long as you remember to swap out equipment. The down side, only works against melee.
