I think they should give each brady a makeover but make them look like their characters. Darken the brady boys hair, put long blonde hair on the girls, except Susan should hair blonde curls in pig tails lol then put them on the stairs.
Also if directors make a show off the younger years, for instance they have bradys grown up, their childern should look exactly like they did as a child, that would make people watch the show. People love to see what they remember
