I love this. I hear a lot of yuyoyuppe type inspiration I think, and you're doing a great job with it.
I got 3 scream layers, One high teto, One low teto, and one mid karin. Each go through roughly: Eq -> charsiesis (the main screaming plugin) -> vocascreamer (not a lot) -> eq -> slight bitcrush. All run through a scream bus with some minor eq
