Would say it would be very stupid to do this! By the way, manipulations like this has in consequence to lose all pretension of insurance in case of an accident even in case you aren't the causer.

Doesn't matter. It is a COPPER ALLOY. DOT says NO. Install it on a vehicle and wait for the lawyers to come calling if anything EVER happens. Just the way it is.
SAE flares and bubble flares are LEGAL. Compression ring style fittings are not.
What's a "DIN" flare? Is that what I'd know as an ISO or "bubble" flare? If so I disagree; a bubble flare can only be disassembled once or twice before it needs replacement.
Best of all would be AN type flares/fittings, but they've never caught on for automotive use for some reason.

DIN are sort of a half ISO bubble. The face looks like a bubble flare but the back has a flat surface. If you start forming a standard double flare and stop after the first step on a manual tool you get the DIN style flare.
You are VERY correct. They are at most a two time use flare. Even then they are a pain to seal the second time. Plus the stress riser at that flat area at the base of the flare makes it easy for vibration to break them.
Looking online I found a few references to the "Kunifer" or "90-10 Copper-Nickel" being marginal for vehicle use due to work hardening from vibration. The only thing I see on the web sites about it are that it doesn't corrode like steel. That is it's claim to fame.
I know a guy who used compression fittings from Home Depot to fix a broken brake line. Stupid, but better than this.
If the rear brake line corroded to the point of being useless, the front line & hoses are probably just as bad.
The rubber brake hoses breakdown internally and can collapse when you depress the brake pedal causing the brake to drag and or not release fully.
If you do disable the rear brakes, it will probably put undo stress on the fronts brakes causing them to work harder to stop the vehicle. When the fronts fail and your on the interstate doing 80 mph try to run into one of the " low boy " semi trailer's, that's the trailer that goes goes almost down to the ground, that way if you hit it you don't go under it.
Fix the brake lines or junk the vehicle and get another car.
Christ, even I replaced my brake hoses on my car with over 300,000 mile, and my vehicle certainly isn't worth fixing any more, but I keep it anyway.
Good Luck,
