That would be a downgraded Playstation Vita with no touch pad on its back.
Seriously though, Nintendo would never do anything like that unless Apple bught them completely (approx. 250 years from now, at the very least). And then this peripheral wouldn't be required to play Nintendo games on iOS.
On top of that, Apple would not go beyond touch-only for their mobile devices.
Of course, anything can happen, but I'd say "no".
