i know you might not like the answer: create another account and since they are likely at 0CP anyways, just beat them with that account. If it helps, only ever use it for this purpose. Otherwise you will possibly never get them back, especially if no one else will do it for you... seriously.
i still think Blissey is relevant. My 38.5 level Blissey doesn't go down that easily, although my Snorlax does. I think you are right overall, exception being Miss Bliss
