DOT 3 is hygroscopic, absorbing of water, and I expect it would suck the water out of mixed coolant, making an unholy globby mess.

If that caused an unholy, globby mess, your brake system, once it absorbed water, would be an unholy, globby mess.
But it isn't.

Its not, at first sight, necessarily crazy, since they are both glycols.
They are different glycols, however, and Shannow's experiment suggests that difference is important. Probably worth a pilot test in a tube first, but eventually you'd have to go live.
Brake fluid seems to make a good carb cleaner, with some advantages over the commercial version. People also use it for piston soaking, though I havn't tried that yet.

Most of you are paying no attention to the post or the OP in this thread. He's more than knowledgeable and isn't seriously considering this, rather just asking a theoretical question. He isn't looking for advice, rather just discussion. Of course I guess that is his mistake, discussing for the sake of discussion on a discussion forum.
throw it on the neighbors new car.

You're joking, right? Different elastomers are used for different fluids, not all are resistant to the same things. You have EPDM coolant hoses? How about your head gasket and other gaskets in contact with coolant? Are they are resistant to brake fluid? If it's a composite radiator how about the plastic end tanks?
How about the heater hoses? What about the little o-rings and seals in your heater valve? Are all those resistant to glycol ethers too? Even if they were, how about at elevated temperatures in the presence of water?

Hair brain idea.
