Messing around with flammable gas burners isn't necessarily the best thing unless you really know what you're doing.

No, it's definitely not. I'm a born tinker but I know when to stop when my butt is on the line.
Well, it could definitely be done. You just need to widen the gap between the bottom of the pot and the top of the burner. Any increase will probably result in a reduction of CO emission.
JUST BE REALLY FREAKING CAREFUL. If you mess up the flow, gas can come
out of the air intake ports on the burner column. You could get some really odd heating, heating that might cause the canister to overheat and might make it difficult to turn off the stove. Apply enough heat to a canister of liquified gas, and... Well, you get the idea. It wouldn't be pretty.
