Ah ok, I did add the text to the save file screen today, just need to do some more testing before I can post it for everyone. For the Game Over, I think you could use [CGMZ] Game Over and change the graphic based on how the player died:

[CGMZ] Game Over is a free plugin, you can try it out and let me know if it works for what you want.
