I wonder - with the "Temple Guardian's Robe" we see the dev team working on that thing actively - as it's no longer a "present/removed" system like with the old cloaks, but it actually features a "hood down" model.
Only issue I've is - it disables the hair on the characters, but due to the hood being so "open" - it makes your non-bald characters/companions look...well, let's just say it's strange.
I've found it problematic to find some unobtrusive headgear, that would toggle the hood down position and not really cover the face too much - especially hard for a light armor wearing rep companion, as apparently all the old circlets have been made to work with "hood up", and the only one left is "consular only" (kind of stupid the companions don't fall into those classes, or those class restrictions aren't removed alltogether.
Anyway, back on topic. My question would be (hopefully - if some dev happens to walk across this thread): would it be possible to add for you some sort of "covert energy" helmet, which would allow you to have the head fully visible, but would work as a "hood down position enforcer" for the, apparently, new line of robes/cloaks?
