If a publisher doesn't want to deal with audience expectations that are naturally and inevitably formed by previously-published material, the way to do that is to not use the same "brand" as the previously-published material. It is the audience expectations that make a "brand" valuable; choosing to tap into that value means choosing to deal with those expectations.
I mean, the Sherlock Holmes canon was written much longer ago, mostly when literally no one currently alive was born, by no being or entity currently producing such stories. And yet that age is irrelevant. Anyone releasing a new "Sherlock Holmes" story today, in whatever medium, does not merely have to deal with the expectations created by those stories, but by doing a "Sherlock Holmes" story in the first place, chose to invoke and deal with those expectations.
That doesn't mean a new story has to strictly adhere to the audience expectations; playing off or against them is a perfectly valid artistic choice. But the audience expectations exist, and, ultimately, those expectations are the only reason to do a "Sherlock Holmes" story at all. The creator owes a half-step more consideration for audience cries of "that didn't meet my expectations" than in a work dealing with original characters in an original setting, because the creator is the one who chose to validate the bringing of the expectations to the work by making it a "Sherlock Holmes" story.
