It may be a bit late for that as the engine is spread between the front room and spare room , and the crank i have has some really deep score lines on it .. see photos
Just found this on RPI website. Re-grounded Crank and new bearings, new piston rings, new mains bolts, new oil pump gears, gaskets as required, the Crank is ground 10/10 to ensure RPi highest standards. £295 . seems ok

Yep after looking around i think mine is not that bad so a good clean, new gears ect and back on it goes . I am thinking if i keep the oil clean there should be a few miles in it yet ...... Paul
