Usually the bearings will last a long time. I would not bother removing any of the system. Why do I say that? Do you ever use the defroster? On most newer vehicles the AC is used during the defrost mode to dry the air and prevent fogging or even icing of the interior of the windshield. So you may be running the compressor even though you do not think you are.
In the event that the clutch idler bearing was to fail they usually make noise first and are not real hard to replace anyway.
