Yanfly Visual Battlers, how to change death character to a coffin?

[Mima 1]

https://www.rpgmakercentral.com/topic/10445-yea-visual-battlers-addon-fix i found this update to yanfly visual battlers script and it make it so that death characters appear in the battle as x sprite in overworld but with a angle instead of before where they would just stay in place.

while that is neat i personally would prefer if the character instead changed into a coffin sprite even if is the default one that comes with rpg maker vx ace, i tried to contact the original creator but it seems they dissapeared from the website for some years now, can someone help me?
