[SEL] Crankshaft extending

I've got an engine where someone took a hacksaw and shortened the
crankshaft for some reason.  Maybe it stuck out too far and they didn't
want to use a belt pulley on it.

I'm wondering if it is feasible to extend the crankshaft, or should I
find replacement crankshaft instead?

What I'm thinking is that I could put the crankshaft on the lathe and
true up where they cut the shaft.  Then center bore the shaft.
Make an extention piece with a stub to fit the bored hole in the
crankshaft.
Press the extention piece in.
Weld the seam.
Then clean up the joint in the lathe.

Does this sound like a feasible way to fix the crankshaft?
