I am remarkably unfamiliar with Sherlock Holms, in its original form. Nearly all that I know about the character comes from a TV show titled Elementary, which clearly took very great liberties with the original character and premise.
Now that is a show that seems to call for being revived. The last season or two had twists that seemed to destroy the premise and set the stage for an unavoidable end to the series, and then, in the very last episode, took a deus ex machina twist to set everything back to what was “normal” for most of the series' run. From that point, it would make perfect sense to continue the series, as if none of the last season or so had ever happened.
