In a word, "no". You must re-index from scratch. Worse, now that you have some segments thinking the fields are docValues and some not and maybe some mixed, I know of no way to un-entangle them.
I'd create a new collection and re-index it entirely, then use collection aliasing to point the applications at the new collection.
