Evolution of Heroes' sprites per weapon + armour level up, a new workshop file ?

[Morwhell]

Indeed, when you upgrade someone's weapon / armor, the armour / weapon 's sprite drawed in a character sheet evolves too, but not on the hero himself ( you walk, fight depress, kill someone showed as a guy with a lvl 4 weapon and a lvl 4 armour all the time ). Why not change that ?

Here's an exemple (I'm using the Flagellant because he's the most simple to explain ) :

The more you upgrade his armor, the more scars he'll get ( and his stress symbol when the armor is at lvl 5 )
The more you upgrade his weapon, the more bloody and spiky his weapon will be.

Another one ? Here's the Hellion :

First levels, her weapon is super rusty and the blade is small. The more you upgrade her weapon, the bigger and sharpened it'll be ( including the second edge of her axe when her weapon in upgraded to lvl 4 )
And, for her armor, it'll be the same. Uncolored (like in the game), small, and quite ugly at lvl 1, big, furry and impressive at lvl 5 !

It could be an awesome idea to add in the workshop... But I really don't know how to do it, and I know there are super talented people here :D ( someone added 5 skins to every single hero in the game, I incredibly love this guy. )

It's just an idea after all ! ^^
