Perk Idea: Locker Warrior (kinda)

Currenty, there are plenty of perks which work well with pallets, windows, chests, generators, even exit gates - things we do interract with every match. But really not so many are based on lockers - "Dance with Me" and "Quick and Quiet" seem just slightly based, as they work with "loud" actions in general. Lockers almost haven't changed a bit from the begining (well, the single change was Huntress update, but I would talk about that a little later - actually that's the point of the thread), they are not that regarding rewarding, as soon as killer find you - you are dead meat. And that's kinda really sad, so I'm suggesting not a really CHANGE, but a PERK especially for our sweet lockers (joking about there's a Dwight in every locker).
As you all know, when Anna came out - each and every locker was loaded with axes, so that way she could recharge her ability. So there is a WEAPON inside of every single locker, that stays on the map regardless is the killer Anna or not. The WEAPON, that could be used only by her... Or is it?

People of the Fog, I'd like to introduce you my Perk suggestion, based fully on the lockers:

"Stand up for yourself"

You stay smart in the most dire situations.
Once per match if the killer found you in a locker - you can stun him with a hatchet for a 2/2.5/3 of seconds to run away.
The perk could not be activated during the chase.

This is not a skillcheck - the killer just get stunned as soon as he openes the closet. It could be a sort of special animation though.

So this is it! You won't be that harmless if found in a locker no more. It could not be used as a "troll" perk, for you will not be able to stun killer during the chase. The only thing that must be well thought about this perk - is not to encourage players to go "afk" until found, as it would lead to free stun for the killer. Should the perk be deactivated if the player is staying still for too long?
So what to you think about this idea in general?
