Forum:Possible to edit out all the spider girls?

My friend loves monster girls very much so of course a game like this would be perfect for him. However, he has a crippling fear of spiders and anything resembling spiders. As this game has a few spider girls in it, like this one:

He is unable to play it. "They're not that bad" is not acceptable for him. Is it at all possible to edit the game files to remove the portraits of the spider girls and all the accompanying CG's and replace them with filler pictures? I searched all of the game files and didn't find any folder containing portraits of the monster girls. So I imagine it would involve opening one of the big files with unknown file types? Does anyone know if this can be done and how I would go about doing it? Thank you.
