Not cheap, but the Paul Moto BMX brakes will let you swap to 700c and use the original canti studs. From the description on the website: "On a Pro sized BMX frame, the Moto BMX brake will work with both Pro and Mini (1⅜") sized rims. It even allows for 700c wheels on mountain bikes designed for 26" wheels."
