I settled with replacing the human ships with them for now. It'll be a lot easier once the mod folder's in use, but for now yeah, that'll do just fine. The first time I tried it I got some really odd effects though, only the Sharlin showed up. I just updated to Beta 3 though and it's working fine now. They're some great looking ships, Coplann. I can't wait to see the Flyer and White Star added. I might even take your cue and see if I can't get some of the Narn and Centauri ships rolling with this.
And Morden, let me know if you need a hand with your data mod. I still have most of the tech trees, ship components and general Babylon-fivery from the work I did on a B5 SEIV mod. Really liking the Order/Chaos take on the Good/Evil alignments.
