Make mannequins NPC storable

With all of the changes to furnishings and their storage capacities, it is no longer beneficial to have a full set of mannequins other than for show. When they were first introduced, they provided the best storage available in a single piece of furniture so I did the quest and subsequently purchased the full set. But now, as I referenced earlier, there are better pieces available for pure storage options and yet I do not want to simply toss any of my mannequins.

To that end, is there any possibility of adding mannequins to one of the lists of NPC storable items? Whether it be with the porter moogle or and event item storer, any way to allow future access to these items would be a nice addition.
