Final Mori
The fact that slugging breaks the balance of the game is not a reason to abandon the idea.
Many players know the situation when the killer laid down two, hung one, could not find the last one and closed the hatch, but survivor just bleed out. This is where the final Mori should be activated.
The survivor is already dead, and the killer has already won. How about making the end of the game faster and more epic?

Or you could let survivors on the ground give up instead, and award the killer hook stages, etc was though they were sacrificed.
Which not only solves your exact scenario but also pretty much every situation where slugging is used to grief or bm.
If last surv is bleeding out AND hatch is closed, while gates was not opened, then collapse should rapidly progress, sacrificing survivor. But on the other hand - if surv managed to escape from killer while laying down.. then maybe killer dont deserve that sacrifice?
