South Adelaide and Port Adelaide would stay the same, and although not the same club the Cocks could take the spot of the old North Adelaide, The Eagles - Woodville, Centrals could be Gawler and maybe the Crows reserves could be the Adelaide Football Club? At least we could have a go at Victoria each week!

From Wikipedia,
In 1877, 12 of South Australia's football clubs met to develop a uniform set of rules and establish a governing body. They formed the South Australian Football Association, the first governing body of its type for football in Australia, and adopted rules similar to those used in Victoria. The inaugural 1877 season was contested by those 12 clubs: South Park, Willunga, Port Adelaide, Adelaide, North Adelaide, Prince Alfred College, Gawler, Kapunda, Bankers, Woodville, South Adelaide and Victorian.
