Could there be a patch so toddlers and children can have "unnatural hair colours"?

While dyeing children's hair is definely a really bad idea in real life, the base game gives you the option of special skintones like green and blue. My blue skinned, blue haired sims can't have blue haired kids, so the "but it's unnatural" part doesn't make any sense. What about aliens, vampires, and other supernaturals that will most likely be added in later expansions?
