They do do a tap that big. A eruo bbtool for chasing out the threads would work. Same tpi and dimaiter. Die wise it would be done on a lathe.
The metal would actually be gone on the hub. All you could do would be to run loads of weld all around the hub, turn it down on a lathe and the redo the threads on the lathe.
