If you set your broadcast and receive settings in game to Voice Only, your Speaking As avatar should change the same way it would if you were using text-only. That way you can still talk with one another, but see the character instead. You can also broadcast video and voice, but only receive voice which would show the other players' avatars (and any avatar changes) on your screen and still allow them to see your video. If you set your broadcast to voice only, that will have your avatar showing instead of video, regardless of the other players' options. Does any of this help with what you're hoping to accomplish?
