Ideas for possible Bloodstained 2 story concept.

I think a sequel for Bloodstained could stand to borrow some concepts from Castlevania Portrait of Ruin(possibly my 2nd favorite under Symphony) and Bloodlines such as more varied environments that involve travelling to different areas. I think that idea could certainly work and fits neatly into the ending of Ritual of the Night "But there are still monsters in the world" where Miriam and Johannes could travel to areas across the world to try and finish them. That or more directly lifted from Portrait with another Demonic castle with portals leading to places all over the world(maybe these portals being the only way out of the castle due to some barrier around it). Just imagine all the places she could visit like Rome(imagining a very large Roman Pantheon indented pattern dome room with the central light, could look awesome with 3D effects), some Middle Eastern area like Egypt(cliche I know), Japan area, etc. I believe this would let the game's artists really go all out with the visual design, making them all look and feel distinctive which I felt Ritual of the Night lacked quite a bit if I'm being totally honest.
