Replying to Making brakes wider by welding it

i don't wanna pay $50 for a wider binding for already super expensive bindings the original brake width is 110 mm i neet to make it 125mm, i am good with metal working so that isn't the issue, the issue is the concept of my idea and if i am the only one who thinks i can do it, i am planning on cutting the brake off right at the 90 degree angle of the brake and extending it 7.5mm on each side and welding on that piece to the brake on each side it seem simple enough, but i want to hear other opinions before i just decide to go cutting up my brakes
