Relegation - As in Soccer- could it work here?

I have disliked soccer for as long as i can remember, but have always liked the idea of relegation and promotion, could such a system work here, I am fully aware that it would never be introduced by the AFL , but its the basic idea that i find appealing. and the promoted side coming from the home state of the relegated side, relegation would be the answer to the same sides at the bottom for numerous years ,what is your opinion
