Well as we have scandal of creation for the rolls in the OP, I don't see why not? Maybe it was in fact treachery that got us our spot, hence the name for whatever reason. Plus, even if Mistrust doesn't make it as a house name, it has to be the name of something or a part of the name, it's too awesome to pass up! And as it currently stands, I'm pretty sure you're the only one against it. Unless Mistrust gets some more hate/other names get more love, I don't think the name should change.
