Even if a .005" oversize piston could be found you'd need to have the cylinders opened up for proper fit since the unworn portion at the bottom would have no clearance. Better at that point to do a proper rebore and fit commonly available oversize pistons. Yes, if taper is minimal you can ream the slight ridge at the top, hone and fit standard rings. Don't forget to closely inspect the ring grooves in the pistons for wear and excessive side clearance...it happens quite often. If all looks good and taper is less than about .007" I've had very good results with new rings, valve job and proper clean up. I've done a lot of engines that way over the years and all ran a long time with no problems.
