You couldn't make it 100% faithful to all Zelda games, but a Zelda dungeon maker sounds perfectly doable. Building on a foundation of the original Zelda, I can see a game where players can set a certain amount rooms per dungeon, bomb-able walls, hidden stairs, amount of hearts per dungeon, what items you start with, which ones you have to find, which bosses you fight, etc...
Granted Zelda games are too drastically different to use the same approach that Super Mario Maker had, but if you simply made different graphic style options, reverse-engineered some 8-bit versions of more modern enemies/bosses/weapons, and a few of Link's skills not found in the NES classic... then yeah, I can totally see it being feasible.
There would be some grumbling among fans, but then again, I've never seen anything that has universal appeal to all Zelda fans. There will always be malcontents, don't let that stand in the way of making an otherwise highly successful game.

@yuwarite There's a rational limit to it, I think. Or there should be.
If something as immaterial as liberties being taken with a brief sentence in a game teeming with dialogue is enough to put people into a foaming frenzy, then it stands to reason that they could never like or condone any but one thing in it's truest, most rudimentary form.
That's a textbook example of autistic behavior.

@yuwarite Just because a number of people engage in crazy behavior, doesn't mean we should stop calling it "crazy".

I wasn't even aware this was a thing.
If people are outraged by something as infinitesimal as this, wait until they discover REAL world problems like war, famine and disease...
