You certainly can, just don't be too sad when they're likely declined, or maybe they're already in the roadmap. There's a tiny chance a suggestion could change how an upcoming predator gets added, but I am otherwise sticking pretty close to what's planned.

Ok, no problem if you don't use them. But here's my ideas
Graveyard/dark spooky area: Ghost or vampire
Forest shrine: Kitsune (Refers to Amelia as her offering)
Cave/underground: Drider
Water: Mermaid (Unique Mechanic of being mostly in the deep water, And you would only be able to really escape when she decides to sleep in shallow water.)
