Yugioh is a bit different to this situation. Yami Yugi isn't a split personality, he's a literal soul inhabiting another person. Killer Frost on the other hand originated from Caitlin.

I'm not exactly opposed to Killer Frost getting her own pace but at the same time I don't see any big need for it either.
