Kill kirito x asuna stone dead because in the end that is what ultimately ruined the series. Also remove anything is basically goes into the category of ITS GOOD BECAUSE THERE IS A GIRL!! ITS JUST LIKE MY YA BOOKS WHERE THE GIRL IS VERY SPECIAL!!
Have it focus wholly on action, plot, science fiction, world building, and survival. If there must be a romance under pain of death then just have it with an AI just to lean harder into the science fiction themes.
Kirito as a character is fine. I think i remember seeing an image floating around where anon realized that he lost most of his fights. I don't keep score but i remember that he was mostly suffering.

There is no harem in it to begin with. Harem is a sexual polyamorous relationship with one male and at a minimum of three women.
