Give Federer a better opponent say Novak would he make the final then?

Gonzalez played good in the first set but completely lost his game especially at start of the 3rd when he should have been able to break to love. Anyway say Roger had Rafa`s side of the draw and he was the one who had to play Novak in semis...what do you think the outcome would be ? Roger would probably pull through but a tough match for sure.
