No, you can't make a meteor superweapon that way. I think it is possible to do by making a clone of the EMP superweapon with a weapon that causes meteors intead, but its very involved and I can't be bothered to explain it to you unless you understand fully how the EMP super weapon works. You don't need to put anything under audiovisual.
