Stripped jet stuck in carb, now what?

2003 30hp Mercury 4-stroke. I am rebuilding the carburetors. The jet (the one that sits underneath the main nozzle) is stuck on 2 of the 3 carbs, and I unfortunately have mangled both pretty good trying to unscrew them. They have slots in the top that are suppose to fit a large flathead. I've removed and clean these parts a lot before. I've never had them so stuck that the force of my unscrewing mangled the brass.

Anyways, I don't care about the jets, as they are $10 to replace. I just want them out.

Things I've tried:
(1) Letting carb cleaner spray soak in around the jet
(2) Soaking the entire upper carb in cleaner dip for 20 minutes, water rinse and air gun dry
(3) EZ-out style screw extractor, the "drill bit" wouldn't catch, just created brass dust
(4) Taking a lighter to heat up the carb housing around the jet. I didn't try very long because I was nervous about the fact that the corrosion sticking the jet in place is basically old gasoline.

Things I've been told to try:
(1) Take a Dremel and slice new slots for another flathead attempt. Not sure why this would change anything if I haven't loosened the jet.
(2) Take a propane hand blow torch and hit the housing again. Not sure if this will win me a Darwin Award or if that hidden corrosion is safely chemically inert.

Anybody got any bright ideas?

At least you could easily see and grab on the remaining material. If this were a recessed jet, that would have been a lot more involved. Glad you did remove in though.
