Upgrade old looks of the NPCs of each Signature stories arc

With the new monthly trend, giving a character spotlight to have their own Signature story arc, would be nice if they upgrade the look of that character starring the arc.
Examples, a Signature arc starring Valkyrie, would come with a visual upgrade, hopefully to a hi-res model, with some unique pieces and not that taller ( this can be applied to Swan as well lol).
I would love if the art team upgraded the looks of all the iconic heroes of Paragon, some of them look really old and low-res, but if its time consuming they can do it monthly with the signature story.
Sign if you agree with the idea
