Hybrid stoves don’t make any practical sense. If you think about it in terms of engineering a product, you have the worst of both worlds: high electrical requirements to support 3 induction burners, and a gas supply is required. It makes installation for a consumer always expensive. Also the product itself is more complex internally, and would cost more, and would sell few units which raises the cost further, and so on..
I’m not sure how I would use my round-bottom wok on an induction burner
You can’t. You have to buy special wok/induction setups: https://www.amazon.com/Induction-14-inch-tempered-precision-temperature/dp/B077GL6BJY/, or use your camp stove when you need a flame.
