That is exactly what a Redux action returns. It's a representation of a diff against the current state. At some point though, that diff has to be applied in some form, either atomically (as currently) or through mutation. Actions trigger the reducer that applies the diff to the store. Basically, I'm not certain exactly what you're getting at.
