You know...Sam Witwer might be able to pull off a pretty good Ganondorf, now that you mention it.
Perhaps.
Still I think he could make for a pretty well spoken Link.
Like imagine his role in The Force Unleashed duology but reduce his angst level by 80% and make it so he isn't as prone to anger.
Have Link be the type of character who speaks only when necessary so we still get that "strong silent" archetype most of the time unless Link actually has something he deems worthy of saying.
But also have the story feature a Personal Interest for Link so that when he is lead to believe that the person who is his personal motivation in the story is dead, we get a scene where Link just gets MAD and goes full ham against the villain or his goons for a scene before reveling that his beloved one is not dead but just wounded.
Bonus points if they set up a sequel by having Dark Link be born from the hatred that Link had in that moment, in reference to Zelda II having Dark Link as the final boss.
Heck, have Sam be both like how in The Force Unleashed he was both the voice of Starkiller and Darth Sideous!
Add more bass to his voice with some slight modulation and have Sam speak in a more threatening and arrogant tone to be the voice of Ganondorf.
