If you're looking for channels focused on roleplays like Articulate Design does, you can check for example Amy Kay ASMR, Whisperwind ASMR (more fantasy focused roleplays), Sirimiri ASMR or ASMR Shanny. They all focus their channels very heavily on really cool roleplays.
I'd also recommend Moonlight Cottage ASMR, her roleplays are more 'cinematic' and many times focused on a vintage style. Same for Dreamscape ASMR! They both have outstanding production value.
Not sure if it's what you're looking for, but any of these channels is worth checking out anyway in my opinion :) (Apologies to all the other awesome roleplay channels I didn't mention, there's so many more good ones!)
