Don't know if there is such addon for CoC as I only take them to help get rid of poltergeists in labs. Quick look up showed this Moddb.com for anomaly and it seems that there is no way to just tweak config files, but have to write a script. Try Drive.google.com it is same script from that addon, but without important npcs, only companions.
By the way, you can give outfits to companions too.
