Even if you had to fatally wound it would not be too late too save the soul. Urahara's plan was to use his Gigai model to save souls on the verge of disintegration (implying they were already fatally damaged). So, if his theory were correct then it should not be impossible. As for hollows killing other hollows, that probably does cause problems as well. In the series it is shown that if a hollow devours a human and/or another hollow then they will become apart of them. This would logically be another reason the Shinigami hunt hollows as not only does their existence threaten the balance, but their devouring of other souls prevents those souls from moving on as well. As for the Fullbringers, it was never stated in the series if their powers destroy souls. In fact, in chapter 480 Mayuri says the Quincies are the only ones capable of removing hollows from existence itself. As for Yhwach's soul distribution power, Haschwalth said that Yhwach needed to impart a piece of his soul on the souls that will come back to him. This does apply to those destroyed by said souls.
