Power variants

I think it would be nice to make it so that killers can choose some minor power variants as an option, much like how survivors can choose an item to bring into their match.

Myers would be really easy to show this off. Allow him to choose scratched mirror/vanity/tuft of hair as variants on his baseline power, just at lower power than the add-on boosted ones. Say, scratched mirror only lets you see auras within 8m or 16m, and the tuft of hair requires you to fully drain 3/4 survivors of evil before it goes off. You can keep the add-ons in-game that allow the killer to still power them up to their current max, and just lock them to the variant that mimics them, much like how survivors can only equip toolbox add-ons to their toolboxes.

I think it'd do a lot to add variance within individual matches, since you wouldn't necessarily know what a killer can do just by seeing them, and it wouldn't be quite as oppressive as having to spend BP every since time you want to change a killer's set at all. This would also allow BHVR to add further customization to their killers in the future, instead of having to go all the way in adding completely new characters for minor changes.
