I found that I had to "unequip" items before swapping them, for the changes to stick. I've also only ever tried swapping "like for like" items - titanite shards for tinanite slabs, chain gauntlets for Wolf Knight gauntlets, etc. There are definitely some limitations to what you can and cannot swap and I'll update the main post as and when I understand those.
I've managed to swap out armour, gems and titanite - I now have the Wolf Knight armour set, +8 weapons and unlimited HP and can finally enjoy the game!
What you say you have discovered has already been discovered time ago
No matter if you come from an inventory an object is enough to change it in all position in the save ( generally is four position) one in equipment , one in inventory, two in storage .......
For create the new slot in storage without have item you need know the position where you want put your item.....
Ex: the inventory start with cosumable and have many slot.......every slot have a binary code...you need know exactly the sequence of byte for create new slots ....i dubt that you know!!!!
For now we be content for swap item with new item
