Xenforo doesn't have a search function. Remember the page?
It's popped up several times, but the basic idea is to have Sardinia be two vertical tiles, and then Corsica diagonally connected NW. This 3 tile land mass will likely not be attached to the Italian mainland. Don't think you'll find a picture that shows this: the iterations with screenshots are either Corsica on the Italian mainland, or Corsica and Sardinia as separate islands.
How'd I miss that? It's been like a year since the switch.
... not so sure about super sized Taiwan and Sri Lanka, but as you say "why not".
