Anyway, Fujino is still dependent on the opinion of the fans. We know this from Fujino's jokes about the "low impact of Asuna's memory change." So if the fans start a riot demanding to "punish the whore" (or there's some oil sheik slapping his face with bundles of dollars), then Fujino will, probably, make (relatively)good ending.
For some reason, there are no other characters in the endings that you have suggested. I think the endings in the game will be divided into low and high "prurience" and, accordingly, whether Kirito stayed with Suguha or not. But the game is almost completely linear and, as it seems to me, the endings will differ in minimal details.
Kirito finds out about the betrayal, but he forgive Asuna and she will continue cheating with Inoda? Of course Kirito is dumb and blind, but he is blind to non-obvious things. If it's pointed out to his face that Asuna cheated on him with Inoda, I think even Kirito will realize that Asuna can't be trusted. And if he forgives her, then he will probably control her and there will be no more trust. Kirito is dumb, but it's unlikely that he can be fooled by the same situation several times (if that were the case, he wouldn't be working with the police). If Asuna doesn't want to be controlled, that's another matter. I'm not defending Kirito, but it's already annoying, to be honest. Fujino is too much abuse by Kirito's stupidity, it has reached the point where Kirito is no longer a character, but just a set of pixels for the player.
In the end, I think there are only three endings between the main three characters - Kirito doesn't know anything, Kirito is a cuckold, and the relationship breaks up (Kirito leaves Asuna or Asuna leaves Kirito, it doesn't matter).
But again, it's worth considering the presence of other characters, unless of course Fujino leaves at least someone alive at the end of the story. It may well be that he snaps his fingers like Thanos and all unnecessary characters will disintegrate into dust.
