If the AFL grows to 20 teams, then I suggest a 3rd SANFL team being the merger of 2 powerful SANFL clubs in Norwood and Sturt - instant 10000 members but this would probably ruin the SANFL beyond repair. Hence my preferred AFL option is to reduce the AFL to 18 teams with the merger of Melbourne and North Melbourne to become the Demon Roos.
Adelaide's too small for a third club (both by population and economy). It's not even in the top three most likely candidates for the 20th team.
Port is a middling club, and I say that with love for the club. Port is a middling club that has taken decades to get where they are. A third SA club would pale in comparison to Port.
It would be an absolute minnow and its crowds would look tiny at Adelaide Oval and there's no suitable mid-sized ground for them to play at.
