Oh yeah, I know it's extremely unlikely, just a personal musing/wish. Also, while most of what you said makes "sense", reminder that most NTR plots usually don't really HAVE to make sense, the scenes with Suguha, especially the ones at the love hotel, were clearly made in the way that despite she just being a sister to him they would evoke a sense of NTR anyway, especially with the many offhand references to her feelings for him, Fujino was clearly aiming for that angle when he made those parts and when he retconned Sugu having confessed to him in Fairy Dance XP Same with what you said for Inoda, while it "makes sense" from a logical point of view, we literally haven't had a single showing of him having done things in that aspect, literally the only showing of his thoughts regarding Asuna's mom so far was that he found her hot and that he could use the video to his advantage, so it could go any way still.
In the end though, it's Fujino who will decide how the story will go and I think splitting it into seemingly "paths" will already make this part's development arguably harder than any other game he has tried before, so whatever we think is moot regarding how he decides to handle the plot in the end.
