I know for certain it's possible to code but how likely and how much difficulty are things I don't know, I'm betting it would be INCREDIBLY hard because it requires the game to tell exactly how many times you loaded a save with his scene in particular which would also require some different things because everyone will have that scene saved in the saves screen somewhere different making it not a "this particular save" thing but a "anytime this dialog is being read/played through needs to get recorded" so it would also have quite a few variables I believe because of that.. but to be fair I'm not a computer coder or professional this is all stuff I'm guessing off what others have said so maybe it's actually kinda easy, all up to Hyao to either confirm or deconfirm.
