A better solution would be to produce a Sleeve and bearing kit for the Crank shaft. The idea is to have two sleeves to rebuild the surface on the shaft and internal surface of the rod and a bearing to match. Grind the existing shaft and rod to match the sleeves and have roller bearings and cage that will replace the warn ones. Yes, you still need to have the shaft pulled apart but now there is a rebuilding sequence that would save warn crankshafts. Use of existing rollers and cages from a motor cycle application could be one source.
I have sleeved the eccentric on the oil pump rod hub with very good results and successful repairs. So this is an achievable goal, and used crank shafts will have value.
