I reckon it should stay the same. Asides from how kickass it is, it actually makes sense considering SS Link managed to obtain the complete Triforce.
Matter of fact, I think most in the game should remain the same, but be buffed or nerfed to fit a balance. Some are obviously lacking, while others can slaughter the game beyond belief. The only cases where they should change completely is to further luigify clone characters, especially the Starfox characters. Falco needs an Arwing.

Fights in Brawl became chases for the Smash Ball which was a major detractor from the great overall balance present in the game.
When items are turned on, game balance is thrown out the window. People chase after any good item, why isolate the Smash Ball? The Home-Run Bat is a one hit KO and an extremely powerful throwing weapon. The dragoon provides easy KOs. The Cracker Launcher and Superspicy curry make it impossible for the character to be approached. I could go on...
