I think it should be beyond obvious now that Fujino has only the most basic bare knowledge of Canon SAO, so yeah, there are countless inconsistencies all around, hell, the mere fact Kirito moved out of his big-ass family home to a shitty apartment is the first one you see that makes absolutely no sense yet nobody really caerd because it was clearly meant for NTR-logic purposes XD
People will keep hoping for that until the very end, no matter how much the plot has been going and showing the exact opposite, because as you recall the majority of people playing this game who know SAO are either SAO or Kirito haters, so yeah

Sadly, there IS still a possibility of Fujino doing that, especially to Sinon (Who has a very real possibility of end up dragging Suguha down with her if she 'falls' like that), so their 'hope' isn't unfounded, even if it would make the whole narrative of Sugu's plot so far pointless Fujino is still at the end of the day an insta-NTR/corruption author at heart with this game being the odd one out, as all the mini-games he released while still doing SAO prove, so he could still do that and the sad reality is that the majority of the game's followers wouldn't give a fuck and still cheer for it :3
