Swaging 1.5" stainless steel tube

I need to increase the ID of the end of a piece of 1.5" x .0625" wall (1.375" ID) stainless steel tube to 1.65". The tube is 900 long, the swaged section is 40 long. I was going to make the appropriate tooling, heat the tube red hot and pull the tool into the tube.



I reckon that should work. Any thoughts or comments before I start?
