I've thought for awhile about a Zelda game about Hyrule in a Modern or Futuristic setting.

Firs thing to consider is the Politics, I think t's be best if Hyrule had become like a Cnstitutional Monarchy, where the Royal Fmaily's sitll there but their nto realy running things.

ANd Maybe, have Ganon become Prime Minister or something and try to make Hyrule a Dictatorship useing some Fake Terorist Attack (Useing Gerudos).
