More ways for killers to get add-ons.

Killers currently have no way to get more add-ons, survivor have a lot of plunder perks, and when playing survivor this is one of the things that give me the most enjoyment in the game, even if i preform less well for doing it.

With there also being a need to give survivors more to do, how about a perk like,
"There are 2 extra chests that spawn, after searching a chest a survivor is revealed to you for 6/7/8 seconds. Every 2 chests plundered you get an addon of rarity very rare or lower."

As a way of the entity creating more dispair with the survivors greed.

But anything that would allow us to get more add-ons on killers that already have all the perks without spending a bunch of bloodpoints would be great.
