So the original frostmourne is shattered, its remains used for artifact weapons.
But we just recently freed (one hand of) the guy who forged it. He could do it again, just not as powerful (maybe some ingredient is missing or sth).
So yeah, it could be possible.
Im just not sure if i want it to happen.
I remember being really excited about getting ashbringer or cool sets like pala t2.
But once i had it like everybody else, i didnt transmog it once because you saw it everywhere
