It is possible but pointless with todays search engines.
A time existed where it was important to get a back link because your sites survival and popularity depended on it, nowadays we have search engines to house site links and do all the ranking and listing in searches.
So your primary goal is to maintain a web presence and keep your site accurate and up to date and the search engines will keep the links updated.

If you can't think outside the box, you will be trapped forever with no escape...
