New Survivor Suggestion
Zeke and Julie from the SNES games Zombies Ate My Neighbors and Ghoul Patrol!
With their experience against monsters and the supernatural, I think these two would be a welcome addition to DBD. It's a shame they haven't seen a new game since 1994.
Some perk suggestions for this character;
Good Neighbor - Each time a survivor is rescued from a hook, repair speed is increased by 2% (Max 12%)
On Patrol - When you keep line of sight on the killer within 16 meters while not repairing a generator for 3 seconds, the killers aura is revealed to all other survivors for 10 seconds.
Exit Strategy - If each survivor has been rescued at least once and the player is the last survivor in the match, an exit door appears (with the same animation as Pyramid Heads Cage of Atonement ability and entered with the locker animation)
