In 1993, a year after the series' cancellation, Heide Perlman proposed a new comedy pilot for ABC which was a re-conceived version of Sibs. Perlman was successful in having Margaret Colin, Jami Gertz and Dan Castellaneta participate in the new pilot, in which all reprised their Sibs characters of Audie, Lily and Warren respectively. ABC greenlighted the pilot, titled Related By Birth, and it was produced later that year. This incarnation focused on the close relationship of sisters Audie and Lily, with no mention as to the existence of older sister Nora or brother-in-law Howie. ABC aired Related By Birth as a summer pilot special on July 2, 1994, but passed on developing the project into a weekly series.
