This will be exciting! And I love the open-ness of Zelda! I think a customizable character would be fun (though I'd play as Link) so you can have a another story to play on. I think maybe for the customer characters they could features from previous Zelda games to make characters more unique. Like twilight abilities and you get your own beast form, or your character dabbles with magic and Masks and they get masks, I think that would be fun.
And if you choose to play as a Custom maybe Link can be your partner?
In theory, the name Link isn't even Link's name rather the name Link is a placeholding name that represents a Link in a family chain of heroes. So rather than playing as Link, he is playing you.
