Instance geo on Niagara particles

I have some actor enemies that need to fall like a space invaders game. I would like to for each particle to instance an actor blueprint which contain specified enemies. They need to be actors because I have setups in them in order for my player to shoot and destroy them as they fall. Can I do this? I have seen some custom geo as static meshes, but I need mine to instance actor blueprints. Under the Mesh Renderer it doesn’t allow me to attach an actor, only static or skeletal meshes.

I haven’t found a good tutorial on this. I’m open to suggestions.
