Even though the concept sounds extremely amusing, you forgot that one of Riot's catchphrases is also that you shouldn't punish an enemy on what would be normally a good rule. Facing a Leona whilst the Regalia is an extremely negative experience for the Leona and is extremely anti-fun for them. The Leona can't use her Q or W or else she gives the person a damaging AOE buff that also has defense or a stun that can also be ranged. The Leona then gets blamed for her actions since she may have thrown the game all because of one item. She can't play around it like a spellshield as it can't be disabled by an ally and since it's an item it can be gotten by more than 1 person on the enemy team.
