This is turning into a rather weird twist. I think the main idea behind Kai 2 instead of Kai Ni is to allow people to pronounce it in their own language, e.g. like how you would pronounce 12.7cm. There's no reason for Kai Ni to be the correct pronounciation because it's just a term that's left untranslated by our predecessors and somehow got stuck until now.

Though I guess adopting Kai 2 will create a problem with people asking wtf does Ni means in the comment section >.>.
