Which Nintendo studio can make a multiplayer FPS game in a scale of COD and hype like Titan Fall?

I guess Retro, they're exprienced in shooters and all that, but the Prime games didn't have mass appeal like titanfall looks to have.
Though what would it be like if The KIU team made an FPS? It'd probably be T-rated and could have potential since most shooters are rated M.
