You think so? A UV zone (so to speak) means your brain essentially shifts into perceiving the world in direct reference to what it feels/knows its body is - which in part means what it's payed essence for. But if a TM brain knows at all that it's been decorpulated (hmmm, what IS the term ...), then there's going to be some serious issues, even in UV. And because the technical expression of SR's rules is not the 'reality' of SR, even if a TM was de-bodied in a UV zone, they may - probably 'will' - get that strong sense that something is wrong, unbalanced. (Because even if you're running Hot VR, your back-brain knows the rest of your body is there. Major, major penalties to act/react in the Real, sure, but still ...)
All in all, I'd keep the ruling that turning someone, even a TM, into a jarhead is going to drop their essence like a rock.
