A subjective answer:
Ultimately, the utility of language is to communicate, sometimes that includes emotional qualia which sometimes depend on apparently faulty phrasing. E.g. "I can't even."
In your case, it is clear that you are trying to be formal and rigorous. If your goal is to conform to certain editorial standards of language usages (e.g. writing for English class), than avoiding redundancy probably helps. However, if you are writing to actually communicate with the readers with the goal of facilitating understanding, using both adjective and verb will be more helpful especially considering most people's unfamiliarity with "dovetail", denotation and connotation alike.
