Can there be a return of Dreadtide Weapons?

Hi,

They used to be in the game and them something caused them to be taken out. I wanted to know if it was possible to bring them back by putting them in an exchange shop or by allowing them to drop from the last boss in Dreadtide Arena or both? They made great weapon skins and it would be nice to have them once again.
Please help.

I didn't find the right solution from the Internet.
