About lore legendaries

Can you make it to where you don’t get any credits for them if you sell them, and in addition, be able to create copies (up to having 1 copy of the item) via going to the character section under challenges? I feel like that would be a better solution, rather than having permanent bank spaces for them, so that people accidentally selling them for some reason can get them back. Or if you just want temporary bank space. And yes, the legendary items gained before the revamp of having set stats for their rolls will be set to those kind if you sell them and then regain them.
