The New Nintendo 3DS was based around this, and although they abandoned it I think there's still a lot of room for something like it. It's more AR than AR is.
It always seemed gimmicky to me, but I’ve heard that the Mario brothers 3D worked a lot better with the depth element than in any of the remakes (I did it enjoy it just fine on my switch)
