Wouldn't need all that many ships actually. When you consider that it's a wormhole, and nobody knows wormholes better than Manticore. Yes the actual "lanes" are big enough that the multi megaton freighters have a very distinct entry and exit lane that allows both incoming and outgoing ships to travel without coming close enough to blow each others nodes.
But if you park what amounts to a wall of rolled superdreadnoughts, you'd only need a dozen-ish to complete a basic wall. Superdreadnought wedges how wide, in addition to being longer than the ship is (and SDs are what, damn near a klick long themselves?)
That makes the wedge something approaching 2 km long, and more than a few km wide. Parked in just far enough out that you don't need a functional hyper generator or sails, you can pretty well block off any incoming travel, without using a ridiculous amount of hulls.
Additionally, ships using wormholes don't go through with zero velocity, so things will coast (slightly). Even the exploratory destroyer for the Astro-whatever bureau it was again had some bleed, and it was creeping into the two wormholes at less than 1 gravity of acceleration, standard velocity is between 10 and 50 I think.
To use another reference, think of a wormhole like the Gates from Mass Effect, and in particular, the Omega Gate in Mass Effect 2. If you recall, the Normandy SR-2 just barely managed to dodge all the dead hulks after transiting, and only because it had a) low mass compared to a larger ship (its only a frigate after all, but in honorverse would be closer to a DD), and b) it had ridiculously overpowered engines (cruiser weight in ME, but it'd be more of a BC wedge on its DD hull)
I could try to dig up a youtube video of the actual clip I mean, but yeah... the Normandy SR-2 when it transited managed to dodge. But had it been a bigger ship (say, a superdreadnought or maybe even a full-up Lenny Det spider ship-fort), would have slammed right into stuff. And if that stuff is a running wedge, and you're only using a sail... I think the wedge mechanic trumps sail, and the incoming ship either gets disintigrated, or they both blow up. And if there's ships transiting behind the first, it turns into a nice big super chain reaction, that lost you one (useless) superdreadnought, with lots and lots of spares that could be slotted in (or cycled out for the minimal maintenance to keep the wedges running).
The only real issue would be occasionally having to use a pinnace to put a crew on ships, to maneuver them away from their picket position, and having enough ships to cycle them for that minimal maintenance.
