I have to admit, that's an impressive job of rationalizing things. Some bits of it hold up better than others, IMHO...
L'rell was a child of two houses (T'Kuvma and Mo'Kai). She said she was bringing Voq to the matriarchs of Mo'Kai, so I assume it is this connection (Mo'Kai and the spymasters and matriarchs) that placed L'rell in command of this ship...
Valid point. Quite possibly Mo'Kai had its own ships and was not beholden to Kor and the House of Kol. But if that's so, how did she wind up working on Kol's own ship after Cornwell was captured?
(See, this is an example of how I think a little more time and attention devoted to internal Klingon politics — preferably
not subtitled! — would not only have been interesting in its own right, but would have really helped make sense out of not just the war
per se but lots of other plots over the course of the season.)
In my understanding, Tyler was dead or near-dead (along with several others?) when the matriarchs found him and stored him. The sex slave stuff was conditioning on Voq after the fact.
Guess I can see that as a possible interpretation, but I don't recall anything actually on-screen to suggest it. (Granted the flashback scenes were deliberately fairly impressionistic, so it's hard to tell what to take literally.)
The spymasters have access to all the technology of the quadrant in order to keep up with the espionage arms race.
Again... what's on-screen as a basis for this supposition? And if it's true, why would L'rell even
need to insert Voq as a new spy, if she already has access to such great intel?
Healing time might be a matter of hours with dermal regenerators, and brain transference of that nature might be beyond their level.
Fair point on the first part of that. (Although if so, you'd think the surgery itself would've looked cleaner too. But again, impressionistic!...) I can't agree on the second part, though... the whole process still had to involve transplanting a consciousness into an occupied brain, whichever direction it went.
Yeah, crazy luck. It's possible that the matriarchs have other contacts/means of manuevering Lorca (or any Starfleet Captain?) into place, but I think the original plan was to just have Tyler escape with whomever and, ideally, he would activate and maneuver things on his end.
Crazy luck? Yeah, you can say that again! It's one thing when characters in fiction succeed at something because luck falls their way (although it still happens frequently enough to be annoying), but it's a whole other thing when the characters' plans
depend on the kind of luck that can only happen by plot contrivance. Otherwise, what would we have here?... "Go wherever with whomever, activate on your own, and try to make the best of it" really isn't much of a plan at all. Which is, I suppose, the whole point of the OP.
I think Tyler was an ambitious program, but it had alot of faults, not helped by the fact that L'rell and Voq hijacked it due to their politicking. I like to think that the Mo'Kai learned from these mistakes, and dozens of perfectly adjusted Klingon spies are working their way through the hallowed halls of Starfleet.
I don't doubt there are other Klingon agents here and there in the Federation. At least, there certainly were a decade later. (We know about Arne Darvin, of course... and the
ST:Vanguard novels made interesting use of one, as well.) I'd imagine most of them are Augment-style Klingons (whether or not DSC acknowledges the existence of same), though, simply because it would make things so much easier. I'd also imagine most of them actually know who they are and what they're doing, for the same reason.
All of that still leaves us wondering about what the point of
L'rell's specific plan for Voq was meant to be. Even setting aside all the crazy plot contrivances, the question still hangs in the air:
what was her endgame meant to be? What
was the "politicking" meant to accomplish? That is anything but clear.
(I'm pretty sure it was never "blackmail my own home planet with a Federation doomsday weapon," though. Which is
another plan that should have never worked...)
