Hobo, think about the torque that twists the splines on the yoke....now think about your grinder leaving nicks or stress risers in the shaft....what you would be trying to do is to make a lathe part using a hand held grinder!! What if you screw up and the shaft breaks? Is that a $100 error? What if the shaft breaks and the yoke goes sideways and takes out the transmission tailhousing/case? That may be at least $3 alone..... If you're asking, my advice is to pony up the $100 and do it right.
