I’d love to see a James Bond-themed Zelda clone. Bond and Link both do odd jobs in different locations using an array of fancy gadgets, you might as well replace the bombs with an exploding pen or something.
The gadget aspect of Zelda really got ratcheted up in Skyward Sword, where you get a remote-controlled flying beetle that can grab stuff and cut ropes for you. Maybe not as elaborate as the zippy camouflaged toy robot from Metal Gear Solid 4, but still pretty fancy for something you get so early in the game.
