Determined Soul Trio

There are 3 alternate timelines of the original Classic Sans, with Determination having changed Them in varying ways.

There is Dust Sans, who gained vast amounts of Determination, through the slaughtering of e people that he had cared about, even his brother.

There is Geno Sans, who had injected DT into his own soul, and had died, forcing him to reside inside of the Save Screen, in order to stay alive in this place.

There is Glitch Sans, who had gained DT through the power of absorbing the soul of the Human Named Frisk, in which he gained far more greater power than ever before.

What happens...if all 3 of these versions of Classic Sans appear on the Judgement Hall, to fight off against the human that had pushed them to this point? The human that became the reason that they are the way they are now?
