Couple of things. First, Kace Auto Loot. It seems if you convert the mod to SkyrimSE, the chest does seem to work a bit. It would be nice if we could manually edit the ID's of what it collects, it could be easier since we don't have an MCM or SkyUI yet. Second, Levellers Tower has a couple of spells, Collector and Harvester. Seems to me some enterprising modder could modify these to be an enchantment that could be placed on a ring... These two options may not be perfect or fast, but they do work and both do a fairly good job for the time being.
