i dont think you could do it,surely the tolerances are too slight. 1/2" is too close to 9/16" the thickness on the wall of the bush (thats what they are called) would be too thin to thread on the inside and the outside.
helicoil just means you cut a deeper thread and then screw in a steel spring (sort of) into it. Its great for putting a steel thread into ally but cos you have to cut it deeper in the first place they wouldnt help this problem.

Good idea. Are the threads the same pitch?

Daz... stick to freshly skinned bulls heads... retapping threads is not your strong point
