That's an interesting idea. I think it would work better as a spinoff than a main Zelda game, like Hyrule Warriors.
And I guess I don't have an exact idea currently of what I would want for a Zelda game right now, XD . Maybe it could be a direct sequel to TP, like MM was to OoT or a prequel or sequel to Skyward Sword, maybe. Or just a totally new idea like yours, but I don't have ideas for a plot atm.
Just focused atm on finding more info about the new Zelda for Wii U. XD
