My quirky brain can imagine that any scenario that might shove the tactic on the table would be very interesting. Not to say a reader's delight in excitement. IMO.
The only thing I can think of is another defender's tactic - sending a pile of ships as a spoiling 'attack' to throw off an attacker's planned transit time. Unfortunately, those ships would require at least some crews and they would be destroyed or surrendered. And advance knowledge of an enemy transit.
There's no getting what you're asking for - any potential attacker inevitably holds the far side of a bridge automatically denies normal usage of said bridge. There is no way for blocking of that bridge to affect any other bridges.
And even Manticore, with the biggest known Junction(hence allowing the largest possible mass transits and the longest lock-down times) can only be locked for a maximum of seventeen hours, at a cost of two hundred million tons of shipping. That's at a cost of 25 SDs or large freighters thrown into the defenders' waiting jaws, unable to retreat. For 17 hours.
By all accounts, RFC carefully set the Honorverse up to prevent any duplication of Starfire's warp point mechanics. Hyperspace was the big one, but how the wormholes work is also far more limited.
