I'm not ruining the idea, it's very clean to use methane but it will need more input than just swapping the fuel etc

Yeah but kero has carbon dioxide that lasts for thousands of years. While methane only stays in the atmosphere for 3 years. I was thinking of a pressurized nozzle which would shoot out methane into the engine then mix the methane with the air by a motor. And than ignite it with a spark igniter.
