BMW V10 S85 Crank Salvage

OK I have already been informed that the V10 Crank can NOT be reclaimed by any means. Yet I have seen reputedly reclaimed Cranks advertised for sale but have had no luck finding anyone who has the capabilities of rebuilding the crankshaft.
Anyone had any experience of having V10 crankshafts reclaimed or rebuilt?

OK found a supplier of 0.25 undersize big end bearings for the V10 crankshaft but all of the crankshaft regrinders in the UK say their wheels are too wide to regrind the crank. Surely someone must be able to get a thinner wheel to get into the journals?
