I don't see why you could not use the trucount pump to supply air to both systems. I dont think the JD air bag pump would be up to the task of running the clutches though. So I guess if my pump for the air bags went south I would just put a valve in the supply line from the trucount compressor to air up the air bags to where they need to be then shut the valve off. As long as the JD pump works, see no reason to take it off.
