See, that's the thing, regardless of if Hebishima is gone or not, the other girls WILL still be around. Suguha and Shino ARE going to have scenes in the game and their own plots already, he made their models and such, he won't scrap them even if Hebishima is scrapped, so I would say a good midway point would be that instead of they being used for a side-plot most people didn't care about then they're better used to fuel Inoda's goal of taking Asuna. After all, Suguha WAS gonna get sex scenes that were NOT "Inoda gets Asuna-focus" anyway, so wouldn't it be better if the plot of writing Hebishima gets removed, which is already less writing, and Suguha's scenes get turned into ways of furthering Asuna falling to Inoda? (Like her getting jealous Inoda is fucking every other girl but her now as she's still chronically longing for his dick) Sure it may not be the ending/route you wanted, but it would still reduce the amount of focus away from Inoda getting Asuna even if by a small margin, and could be used to add even more Asuna/Inoda content really (Like making it so that there are 2 or more girls during "fights" so that one or more could "block" Kirito's view while Inoda molests or outright fucks Asuna, for example).
