I have not looked at the larger bearing, but from what I've seen in passing there is little problem with them in the base, thought some say their reliability can be improved by removing the grease seal and relying on splash or DOF. If I had one of them I'd be tempted to leave it alone. When replacing my IMS I searched a long time to replace it with a shaft using the 6204 bearing so it could be serviced. I'm not sure that was the best choice.
As far as drilling the hole with the shaft in the engine, for the removable (6204) bearing, with the bearing removed a very small 90 degree drill bit drive with a predetermined set back would need to be built. Not impossible, but not easy either. Milwaukee makes one commercially that is close, but I think it would be custom tooling to drill from the inside of the shaft.
