Reagent Restocker had the ability to stock in your inventory a certain number of items, even add to or take from your bank (I don't remember if you had to click a 'restock' button or not, but still..). I do think this idea is possible as a plug in to another addon such as RR (to save time from coding from scratch.. if RR is even still current). I don't think it's possible to combine the quest items, however. That would require an actual hardware event.
The issue here, would be how to make the addon update which items were needed from bank. If it's managed properly, I think it would be a great Daily addon, not just for JC.
Like Xrystal, I'm not currently playing either though.
