Storeable/Delivery box Relic/mythic/empy

I would like to reclaim some of my inventory space from these legendary weapons either by a moogle slip or by allowing me to move them to a mule.

With most people wanting relic/empy/mythic jobs to participate in most events its become more and more essential to gear multiple jobs with these weapons to the point where for some of us its taking up 10-15 slots and with the ammount of gear needed to gear most jobs that is not storable (most jobs taking up 70+ slots) I already have issues just keeping 4 of my jobs on me at a time so I would not mind freeing up a bunch of slots by being able to store or mule the weapons I wont be needing currently so I may hold more of my voidwatch logs and the 90000 voiddusts I need to carry because they will never be made stackable for balance reasons.
