ALTER TABLE articles ADD COLUMN ptr int;

Then add a field on edit article page that lets you point to a different article, and update render code to check it...

def render_article(id)
  article = Article.find(id)
  return render_article(article.ptr) if article.ptr.present?

  //renders article
end

it's a hack, but it buys 8 years of good will back whilst you work on a proper solution?
