Hello Yago, To my knowledge, in facet calculations docValues take precedence over other methods. So, even if your field is also stored and indexed, your facets won't use the inverted index or fieldValueCache, when docValues are present.
I think you will still have to store and index to maintain your other functionality. DocValues are helpful only for facets and sorting to my knowledge.
