I have seen it done by the hot rod guys and the stock car fraternity when they shorten a half shaft to avoid the hassle of re-splining it after shortening. Minimal spigot both in diameter and length of, vee'd out, set up between centres, tacked up, multi-pass welded with the appropriate electrodes and machined. Sounds rough as, and not to my taste, but it works fine even with a big V8 on the other end.
Agreed.
I guess that that you could use the new taper part, shorten it slightly and recut another knackered half shaft and do it property.
All it needs is a lathe and a tig. I did much the same to replace the motor on a Bridgeport milling machine.
