Uggh wish I could give a positive yes or no bro. I'm not really a metallurgical expert. So basically you are thinking of taking an alloy tube that just fits the inside of the head tube with some sort of bonding material to make it a permanent "weld". Then take some sort of rings that would over lap the outside of the head tube but go inside of the sleeved tube that would be bonded as well?
Correct me if I am wrong but can there be micro cracks that run along the main crack in the head tube, like ones invisible to the naked eye?. Might be do able but one would have to ride VERY carefully on it. That is one of the major stress point of a bicycle if I am thinking right. You might get away with it for a while but the metal is already weakened and has a tear in it. My thoughts to make a very good repair is the idea you have and well the real welding of the crack. That may hold up pretty good, providing the welder know what the heck they are doing!
Sorry I really do not have anything else to contribute.
