Sorry, thermodynamics would not agree with you. There are very few losses when converting natural gas to high entropy heat. Many losses when converting natural gas to high entropy heat, then to low entropy electricity, transmitting it and finally converting back to high entropy heat.
Of course the carbon footprint of an electric stove could be lower if powered by nuclear, wind or solar.

- leguminous 4y agoWhat kills the efficiency of gas stoves is not converting gas to heat, it's getting the heat into the pan. Induction stoves heat the pan directly. Gas stoves heat the air, which then has to heat the pan. Inductions stoves can be 90% efficient while gas is more like 40% [1]. Even if your electric company is using gas to generate electricity, generation and transmission losses can be low enough that you'd actually use less gas to power an induction stove than a gas stove. What complicates things somewhat is that the extra energy goes into heating your house (if it is not effectively removed by a venting range hood). In the winter you may not be concerned about that, but in the summer it means you would spend more on air conditioning.
