It'd be pointless to make "Link" a girl, but I wouldn't care if the option to play a female protagonist isn't "Link." Just not "Linkle" because the name's dumb and she looks stupid.
I'd much rather Link talk, given the lesser of two evils. I don't really care what he sounds like. It would be as pointless, if not arguably more so, than making Link a chick, but he's already a defined character. He's got enough personality by now and in each game to give him a voice. I don't know what he'd have to say because it's completely unnecessary for him to say anything, but whatever.
