New hatch/black lock mechanic idea

Currently, the game has an option for the last survivor to find a way out, which is the black lock/hatch.
But the situation is, if killer found the hatch first, they probably gonna camp it, and when the survivor appears, they know that it's impossible to escape through the hatch in front of the killer. That is a huge problem, from now they will hold on forever until one gives up, and that's is not balanced as well as time-consuming.
Here I have an idea for a new hatch mechanic:
Basically, it should have multiple hatches in a map
For 4 survivors left in the trial, 0 hatch appears
For 3 survivors left in the trial, 1 hatch appears
For 2 survivors left in the trial, 2 hatches appear
For 1 survivor left in the trial, 3 hatches appear
And how is it applied?
To make the hatch available, survivors need to
Repair 4 generators if 3 survivors are still alive
Repair 3 generators if 2 survivors are still alive
Repair 2 generators if 1 survivor is still alive
Hold on, those hatches should not be opened all at once. About this part, even though the last survivor has 3 hatches to escape, only 1 is opened.
And still, not until the last person left alone in the map does the hatch open. But this time, the killer can close the lid of any hatch in the map at will or else the hatch will automatically shut down after 120 seconds. Whenever one hatch is closed, another one will be opened randomly. It should act like jigsaw's boxes, random is as random does.
Tweak to involved items:
Skeleton key ( pink, ultra-rare item ) is now a master key, it can open any visible hatch in the map. But with a condition, the hatch that the skeleton key goes in, will be closed after 2 people have gone through or expired after 60 seconds.
Dull key ( purple, very rare item ) is now a normal key, it attaches to one specific hatch in the map, survivors must find a correct combination to open it. The hatch that the dull key goes in, will immediately be closed after 1 person has gone through or expired after 30 seconds.
Broken key ( green, rare item ) stays the same, not able to unlock any hatch but can channel some effects with add-ons for keys.
Updated animation: Separated unlocking action from jumping into the black lock. Which means you can use a key to open a hatch but escape or not depending on you.
About those numbers above, devs can optimize them depending on current situation of the game.

Imma just nitpick this really quick

Skeleton key ( pink, ultra-rare item ) is now a master key, it can open any visible hatch in the map. But with a condition, the hatch that the skeleton key goes in, will be closed after 2 people have gone through or expired after 60 seconds.

So how do we do the achievement? Or does it get changed? The "Where did they go"

Idk, haven't thought of that achievement yet. Um, maybe it should change to "Open a hatch to save 2 survivors and then yourself end up with hatch escape"
