Found it, it is part of a 5 book series:

He also had a pretty fun crossover between JAG and Farscape, btw:

Well, IMHO Galactica was always something...
How do you deconstruct what is already a deconstruction?
I am pretty sure RDM wanted an anti-Trek/darker and edgier and more plausible scifi.
I think it, Farscape and Lexxx were prime examples of that.
Which reminds me, I think AlbertG was writing a fairly interesting Farscape/Babylon 5...
Eh, I like to have some space combat, and stomping the Boneheads never gets old.
Besides, I was the stompfic thread's champion when a few of the pretentious prick reetards started raging about it back in the day. :D
But stompfics should be short and end once Bonehead Prime is blown to bits...
Quite good, but how did the Old Ones miss what was happening in the Origin system?
I mean all the weird shit the Orokin did, as well as the Sentients in Alpha Centauri?
What happened with them and the Lotus, btw?
Were the Orokin some type of Old Ones themselves, sheltering Sol from the prying...
Crusade, that was a series with a lot of wasted potential IMO.
Although after a certain point in the SG timeline IMHO, SG crossovers with B5 become less interesting because of the massive power disparity.
That sounds kinda interesting, and somewhat familiar, was it posted to AO3 or ff.net...
Humm, the one where the Prometheus ended up in B5verse during the Shadow War, or the one where the EA found the Stargate and had super-advanced tech camouflaged as their old stuff?
As a certain Scottish alcoholic loves to say. "Naah, it is gonna be fine..."
Was that the one where Babylon 5 actually overpowered Star Trek ships and there were Star Trek Shadows?
EDIT: EXPANDING THIS TO COVER ALL BABYLON 5 CROSSOVERS BY POPULAR DEMAND!
Once upon a time, in a forum far away Trek/B5 fanfics were a sort of fanfiction subgenre of their own, and they were quite wonderful.
Now, though, that crossover subgenre seems somewhat dormant, which is a real shame.
SO...
