[i]Yes!

As a group I wanted us to decide whether we wanted (as you exampled) 
A) Silly - ie: Cant see the color blue
B) Serious - ie: Vomiting fits

This wouldn't be everyone receiving these same effects- but based on your Mahlimae choice something unique.

For the most part they would remain normal humans, but definitely side effects could be shown to create something of more of a supernatural effect- for each category. Something that comes into mind are those "Useless super power" things where it's like "So and so can teleport wherever they want freely but they always end up there naked" 

I hope that all makes sense, and I'm glad you like my jumbled up idea :) lol![/i]
