I agree that stainless steel is nice stuff to use, but I'm not sure it has the same strength as the tubing the OEM specified. I'd tread with caution in making any changes away from approved brake tubing. Perhaps someone with some strength of materials data would look this stuff up. Problem with these descriptions ("copper, steel, stainless") is that we don't know the alloy (for steel or stainless) or the heat treat history of these materials, and I'm paranoid about venturing too far away from what I know is approved for brake service.
