If your heat control is half decent you should be able to concentrate most of the heat into the braze on and leave the tube unaffected.
When I said it was possible to deform the tube I was really meaning locally like putting a little dimple or pulling a bit higher as you manipulate the braze on of the tube rather than alignment type stuff.
