How about we take a page from the mini-addons, like A Shantotto Ascension, or A Moogle Kupo-detat, or A Crystaline prophecy. Lets make this quested, Rare/ex (or atleast EX) and Upon completion, make it have 3 slots and a list of selectable augments, could make it lv 75 or higher. And augments could be based on the base component staffs. Upon completion of the Quest you pick 3 augments for it.

Such as...

-Attack/ranged attack +15
-Critical hit rate/damage +15%
-Physical/magical damage taken -20%
-Cure potency/Cast time +10%/-10%
-MP/HP recovered while healing +10 (or perhaps some refresh?)
-Enhancing/enfeebling/elemental skill +15?
-Evasion/accuracy +15

Or so-forth. It prevents needing a crafter, it could be signed with your name upon completion, and it makes it unprofitable. Also can make it so the quest can be undertaken again with the staff discarded incase the selected stats nolonger benefit the player. Seems the best option for me. The real question is what would the quest need, and should it be hard, or easy. I think a reasonable option could be say...all the avatar whispers or mini-forks or something. Something quick to do since this is for convenience, not perfectionism and elitism.
