I’m more or less in agreement with points 1, 3, and 5.
Dog-face: I’m not native in English, but I’m not sure this conveys the idea of shamelessness implied in κυνώπης.
Per: In Homeric poetry homosexual themes are generally suppressed. In the Iliad (20.233–235) Zeus abducts Ganymedes just to serve him wine, while in other sources Zeus makes him his lover. (http://discourse.textkit.com/t/sleeping-beneath-the-portico/11495/1 here’s a very old thread where we discussed this among other things). I don’t think there’s any explicit hint of homosexuality between Achilles and Patroclus in the Iliad, although later Greek chose to interpret it that way.
In Vol VI in the Cambridge commentary to the Iliad, Nicholas Richardson notes: “In 130 περ must be taken as emphasizing the whole phrase γυναικί … μίσγεσθαι”, and I agree.
