Small corner-mounted induction coils on oven enclosures that are both hyperconductive and well-insulated could be more efficient in terms radiant and convective oven heating.
Induction doesn't work directly on food, though — only on the (ferromagnetic) metal of the pan or enclosure. And the food in the oven doesn't touch the walls. So you're just heating the air in the enclosure a different way.
