Why could you not combine this feature with a simple, non-sealed single row ball bearing? A ball bearing may be a better solution than a roller bearing and the cost could be minimal depending on the source of the bearing.
I have never seen this option discussed anywhere.

Perhaps because the oil pump drives in these engine's are already notoriously weak before you grind a slot in them, punching a hole with a hammer in the pump end shaft seal may not be the best way to control oil flow, and running a flooded IMS shaft may not be the best approach to extending bearing life.
