I wonder, is it possible to do Mark and Recall on the target? Or the Interventions? So that if you hit them, THEY get teleported away?
Unfortunately, it does not work. When an NPC uses any teleportation spell, or any teleportation spell affects them, the spell effect sparkles happen but they stay where they are. Using the console or construction set you can test this out, I have. The only way to make an NPC actually be affected by a teleportation spell you have to use scripting to fake it.
