That would be pretty cool, but tricky to pull off. Currently, Zanz only lets players interact directly on their own turns. So when a player targets a creature you own, you wouldn't be able to interact at all since it would be on the opponent's turn... There would have to be some mechanism of setting up the redirection ahead of time... Since this is a spell, that would probably mean it would get fixed when the spell is cast (likely this would be done through a buff, or in this case set of distinct buffs probably).
