pouches are small enough to put behind most things and not be seen, except by circle of transparency or holding down CTRL-SHIFT to get the object handles to come up.
All you need with that is to find some place that's totally in disuse, mark it for each of your characters (or get all the characters logged out at the same spot, if it's a safe location), then put the pouch behind a tree or piece of furniture.
This was a common tactic for Fel miners to deposit ore, prior to the fire beetle, and some still do it with the ingots from the fire beetle, to stay out longer. Mine, then take the ore or ingots to a hidden pouch, recall home when the pouch full (or fill 4 pouches, fetch a bonded pack animal, load the animal, and recall home). Nothing screams defenseless miner like a pack animal in tow, hence the subterfuge and only havign the packie out for the pickup.
