As far as I know, there haven't been any Sherlock Holmes comic books, have there?
If you'd asked me that two months ago, I wouldn't have known the answer, but:

...and at other times I find the modernism, be it locations or situations or even objects, tend to clash with the ideology.
Could you elaborate on what you mean by that? The only clash I see is that it's harder to justify the idea of Holmes as something special than it was in the Victorian age, because now the forensic science that Holmes (and Doyle) pioneered has become a universal police practice.
Changing the names would make perfect sense, just as it has with every other Holmes pastiche from House to Psych.
That's not the same thing, any more than
West Side Story is the same thing as Baz Luhrmann's
Romeo + Juliet. This isn't just a pastiche, it is
Sherlock Holmes. Same characters, just a different era.
These characters may be derived from the originals, but here we have a main character who is a will-he-or-won't-he-kill-just-out-of-boredom sociopath...
No, we don't. We have a main character who is
alleged to be a potential killer
by someone who dislikes him. You can't take every sentence uttered by every character as gospel fact. It was just one woman's opinion. And you're getting it wrong -- she accused him of being a
psychopath, and Holmes later corrected her that he's actually a high-functioning
sociopath, which is a rather different thing. So not only was it just her opinion, but it was a misinformed opinion.
and a physician sidekick so twisted by war that he gets the jitters without it (and has no problem with cold-bloodedly executing people).
On the former point, both Watsons are veterans of war in Afghanistan and both sustained wounds there. It's just that a modern treatment of the character is bound to be more psychologically nuanced. Had Moffat written a Victorian-era John Watson, he probably would've written him the same way.
On the second point, Doyle's Watson was explicitly described as a crack shot, a superb marksman. He often made use of his service revolver in their cases, and was surely just as stoic about it afterward, because he was a trained soldier.
These are the same characters, at least as much as Bruce Timm's Batman and Christopher Nolan's Batman are the same character. The fact that there are differences in interpretation doesn't make them different characters, just different spins on the same characters.
I do think some characters belong in certain times and places-- certainly they don't belong in certain times and places. Would you reimagine Flash Gordon in the Pleistocene, Odysseus in Hoboken, the Scarlet Pimpernel in the Roaring 20s or the Lone Ranger in Boston?
Flash Gordon quickly leaves the place of his origin for an exotic alien world, so he could come from any Industrial-Age time period. And indeed Flash Gordon has been updated as a "present-day" character more than once -- in the 1980 movie, 1986's
Defenders of the Earth, the 1996 animated series, the 2007 live-action series, and, I believe, in various comics as well. And the 1950s TV series put Flash, Dale, and Zarkov in the 33rd century.
As for Odysseus, he's just a guy trying to get home to his wife. That tale could easily be told as, say, an epic space opera or a Western. As for the Scarlet Pimpernel, that could be done in any bloody revolution, perhaps a post-apocalyptic updating or something in the Russian Revolution. The Lone Ranger could maybe work in a futuristic frontier setting. (In my initial version of the post, I mentioned Zorro and Batman as updatings of the Pimpernel and the Green Hornet as both a conceptual and biological descendant of the Lone Ranger, but those count as similar characters, not updatings of the same characters.)
Some characters have wider ranges; James Bond is a spy, so there are a good many decades he would be at home in.
And Holmes is the world's greatest detective, an antisocial genius and a drug addict. There's nothing about who he is that requires him to be in the Victorian Era. (Yes, as I said, his forensics skills aren't as unique in a later era, but that can be worked around.)
That was unfortunate, but the movies did a good job of holding on to the Holmes ambiance. Of course, they were less than fifty years removed from Holmes's time, not over a hundred as we are now; and the years since WWII have been infinitely more eventful, culturally speaking, than the first part of the century.
Easy to say that in retrospect. We always assume less stuff happened in the past because a lot of it doesn't get written down or remembered. But keep in mind that the people who lived in the '40s considered their era every bit as modern as we consider ours, and no doubt saw great social and cultural foment in the preceding decades. Everyone thinks their own time is special and that all the past is kind of blended together.
