Just as a thought. I personally don't agree that Mary Kelly (the last victim, although the names Mary and Kelly crop up in other parts of the sequence) was not a Ripper victim.
However, the circumstances of her murder were somewhat different to the other (3 to 7) murders attributed to JtR. If she wasn't a Ripper victim, does that not put Tumblety and his apparent interest in female organs right in the frame?

It's not unknown for a homosexual male to have a morbid non-sexual interest in female anatomy.
I don't subscribe to this theory (or any other, frankly) but it is an interesting possibility.
I agree, MJK is more than likely a JTR victim.
IMHO, MJK is a stronger candidate than Stride as a victim.
However, I think Tumblety is an entirely fanciful candidate for JTR.
While there is an argument that a killer can go outside their usual victim pattern, such as you have observed, the sheer prominence of Tumblety in the East End precludes him.
He was a six-foot or so figure, with a broad American accent, fashionably dressed in the latest clobber and sporting a large handlebar mustache. While the eye witness testimony for a suspect is conflicting, there isn't a single acount of anyone remotely fitting this description.
Bearing in mind the average height of someone in the East End would have been between 5' 5" and 5' 7", so someone 6' or over would have been visible from the other end of the street.
What's more, Tumblety, when he did come to police attention, was generally easy to track, until he gave them the slip and headed for the boat. Even then, he was reacquired and tracked on board to be intercepted on landing.
He was a canny mountebank, and probably a mysoginist, but he is very unlikely to be JTR, unless he was a secret master of disguise. for which survives no evidence at all.
