The cotton thread makes sense since you probably want them to fall off. But that being said It would be kind of cool to have " Hoosier " permanently embedded in my chest.

When I was racing in series that required patches, I used cotton thread hand sewn though the outer layer (not shown in your list of options). I fail to see how some thin cotton thread burning away is a "safety" problem. If you are in the middle of a fire, the cotton thread holding your patches on is the absolute LEAST of your worries.
In the end, you're over thinking this.

Switch to Carbon-X...it also wicks moisture and provides another layer of fire protection. Even a standard nomex T-shirt does a pretty good job of moving moisture away from your body. I'd rather not have low-temp melting fabric on underneath my suit. Would suck to survive the fire only to have a layer of plastic melted to my body while the medics try to treat my burns.

Keep in mind that the level of protection we get from race suits is measured in very low number seconds. They do not work like fireman gear or stunt suits in the movies. By the time the patch catches fire and falls off from the thread burning through you are toast.

I figure with my current 3 layer setup and carbonX undies I have about 10 seconds to 1st degree and 20 seconds to some second degrees and 30 seconds to a long stay in the burn unit.

Hence the reason I care more about the 'joints' where there is the least amount of protection. I'm very methodical about tucking the cuff of the pants into the boots and the cuff of the sleeves under the gloves.

They melt pretty quickly but probably not in the time it will take you to exit the car. They certainly don't melt instantly when exposed to heat the way a poly moisture wicking shirt does. That said, you still want them on the OUTSIDE of your cotton shirt. Or preferably, buy one of the nomex or carbon-x cool shirts.
