With the new sets from cannith area, they made some slots more need it than others, how about adding a choice to transfer the enchanments from accesories between each other Via perhaps an elixir from the store, all enchanments would tranfer and the old one get destroyed in the process.
Since both items would be BtC there wouldnt be an xploit or abuse. And by being sold on the store it would limit the ammount of people being able to do so.
