Not sure, despite Ishida disliking Shinigami, I cannot imagine he is all too happy about the new style Quincy. Remember that his grandfather taught him the old-fashioned ways. There are still several other motives as to why he should hate Yhwach aside from his mother being killed by Yhwach himself. I think it would be rather interesting if Ishida is willing to give his life in order to save the world. Perhaps it is just that the right moment wouldn't be the one now. Until then he might stay on the dark side.
