CAS parts changing textures according to sim’s emotions?

i have a project in mind that i would like to realise in future, but i’m not sure it’s technically possible to do in the Sims.

so, what i want to make is like a CAS part (accessory, hat to be precise) which will change it’s appearance with the sim’s emotions. i know there’s a similar feature with the servo bots, however i’m not sure whether it’s realisable with human sims?

if there’s a way to do that, i’d be very grateful for any advice/explanations/help
