The things I see..

In Canada it is illegal and if you are stop for a road inspection you will be grounded until it is replace.

A road rock could pierce the copper tubing and especially with the CMP one chamber master cylinder you cannot take a chance.

Today brake steel tubing are available and they are very flexible.

If you want I could give you a brand of tubing that you do not require tool to bend and it does a job better than the original.

I used to be a salesman and these tubing were one of the product I was selling.
