With some thought, I am actually thinking about what they could do with Sanrio. And as I watch Aggretsuko, I notice how the art-style of the environments acts as if it's a mix between modern and cartoon with Japanese flair.
I would wonder if that's the way they are going to go if Sanrio does get a land, as that could compensate instead of being pinkish buildings.
Mix some of Aggretsuko's designs with the elements of characters of Hello Kitty, Chococat, Badtz-Maru, Kero Kero, and I think you could have a great way to bring Sanrio to the park's in a larger presence, especially if it's moving to Gate 4 in plans.
