This isnt about league , but what if Link and Dark Link fused?

So, what if Link and DLink fused? I searched around a bit and it seems NOBODY on the internet has thought of this yet. Anybody wonder how cool it would be if Link and DLink had to work together throughout a Zelda game to beat a common foe?! The concept is AMAZING, just think of all the things Nintendo could put together for a game like that! JOLLY CO-OPERATION
