I don't believe a change in technique or racquet size would have helped him much in those FO finals. Nadal was a beast in his physical prime and certainly much much more attuned to the surface. Interesting take nevertheless.
Back then, he wasn't as good as he turned out to be.
But I severely doubt that Federer would be FEDERER if he had a 2 handed backhand. And it's not just for asthetic reasons.
