Disabled sims

I texted one creator here already about it cuz SERIOUSLY seeing such talented people here I can't believe noone got that mod idea- I was thinking about mod adding wheelchair in cas as lower part of body, since Grim can kinda fly- why don't use that animation so sim could kinda use wheelchair in game (removing black clous effect that is) I know idea will sounds complicated but.... there's many people simming who waits for it, we do have almost everything in game with mods now... still sims stays all healthy and I can't believe noone decided to start that challenge (and before you'll write to me to do it myself I'm too stupid to be modder)
