Scored Main Cap Bearing - Ouch

So let me ask a really crazy question. If the only journal that needs some polishing is the rear main can I go ahead and just replace all the bearings, clean up the rear journal and grind off the flywheel bolts. This mtr is on its second oil change and I am wondering if all this happen 4-500 miles ago. Of course some has probably happen since but I'm think that most of it happen on initial startup and break in. I am going to pull the oil filter and cut the top and look at the element. What do you all think about this? I would also check the oil holes in crank for chamfer and cleanliness.
