I know you didn't ask me but that's how I would do it if I were to pray it, per my understanding of the introduction in the book. (Using pride as an example)
Maybe, except the prayers shouldn't be in there in their unmodified form at all, in the first place, period.
I just pray to Our Lady, my Guardian Angel, and St. Michael to war off any and all evil spirits.
Now, deprecatory adjuration of the Guardian Angels of those under our authority might in fact be a worthwhile endeavor, as, unlike the evil spirits, they are very much inclined to enforce the authority we have over our loved ones.
