Could I? Yes, easily. Would I? Probably not.
If you've ever seen any of the speed runs of these games, it's possible to beat them in a few hours. Add a few hours to each game if you are playing at a semi-quick pace and it isn't that hard. Assuming that they aren't beating any of the games 100% (i.e. not unlocking every item, just beating the main game) it isn't that hard.
It's not like any of the Zelda games are particularly difficult, especially on your second go-round.
