I’m pretty sure you can match it perfectly. You’d want to use flat colour textures and then use the cel shader to eliminate any native lighting and reintroduce the new simple lighting effect. You’d also use both outline options, depth and detail.
One thing you’d definitely have to do as well is adjust the normals on the character faces to be parallel. That’s a bit fiddly but that’s how you get the ultra-flat look around the faces.
I’ve been working on an anime sample scene that will look a bit like what you’re making, I’ll post some screenshots soon if you’d like to wait.
