Still hoping for castlevania legendaries

Ill admit they put allot of castlevania content in one big package, but i was really hoping to play as simon belmont and shanoa as atleast legendaries. So im holding onto hope that they may still add them in like how the silent hill chapter kept expanding. But seeing as those 2 were alredy put in as cosplays my hope is very slim lol. I am curious though as to why its the first chapter since the attack on titan collab that they just made most of the characters into cosplays for others.
