Admins kinda already got wall hacks. Spectate shows you where all players are already, on top of their health. And as for admins cheating they can set their own HP, on top of giving themselves guns(like you'd know if they bought vs spawned in anything except special tier guns), on top of making themselves not just get shot at by droids. If admins want to they can easily cheat. I don't think this is the best reason to -1 this IMO. Staff members have these powers because they more or less are trusted with them, if they're found to be abusing well... just look at some of the banned staff power abusers.
I'm gonna +1 with the knowledge the the dev team usually denies things that cause lag or are hard to do, because those are my two concerns always. If this is able to happen and to be made to happen quickly then I see no reason why not, if not they'll just deny it.
