Endor, something happens in hyperspace, harmlessly tossing
the ships hundreds of millions of light years away in a matter
of minutes.
The fleet emerges on the edge of Borg space, on the "line" between
the Beta and Delta Quadrants, circa 2376. Almost immediately, the Rebels encounter a manned Borg probeship. The ship hails the fleet,
but in place of the usual "We're going to assimilate you" spiel, we find the ship is piloted by the rogue/liberated Borg from "Unimatrix Zero,"
with a crew eager to learn about the giant, powerful Mon Cal cruisers.
We learn that the Rebels are anxious to return home, of course,
to destroy Death Star II. They realize that Gen. Solo's strike force would probably be eliminated without support from the fleet, but time is
still of the essence: the DSII will be operational in...oh, say, six weeks.
The liberated Borg ship is in contact with a captured tactical cube, on which we find the George Costanza "Think Tank" dude (assimilated shortly after its encounter with VGR), one of the leaders of the rogue drones. We'll lift the title "Cooperative" from VGR season three to describe the rogue Borg.
George, or whatever Jason Alex. character's name was, has an idea to
get the Rebels home--probably some dimensional rift akin to
how the Borg entered Eight-space. However, he is not willing to share
this information with the Rebels unless they help him exterminate
the "true" Borg.
For the sake of this debate, let's say the Rebels conditionally agree (they'll expect these drones to use some Treknology to try to help them later at Endor). So we have the Rebel fleet, assisted by a few dozen Cooperative combat and support ships, geared up to attack the Collective. The
main target is the primary unicomplex, but it is heavily defended. It
is also expected that, following the assimilation of Think Tank Costanza,
the Borg started using neutronium-based hull "armor" (yeah, yeah,
I know

attempting as much.)
How should the Rebels proceed? The Cooperative has incomplete
knowledge of Borg space, but they *do* know where most of
the important installations are; e.g., transwarp hubs and unicomplex
systems. They share this information with the Rebels, naturally.
I realize that's a bit complex, but I was sorta thinking out a possible
fan fic I could write. I always wanted to tie in a few of VGR's better
ideas into a SW vs. ST scenario and make them better
