Tools like the Open Access button (openaccessbutton.org) can be used to search for OA versions of articles - we link to this from the TWL navbox on English, and I believe on a couple of other languages. Updating the link would likely require the use of a bot, and I'm not sure how easy that would be to do automatically.
Cheers,
Nikki
