This is the problem with trying to fit one "universe" into another.
SE is based mostly on a game called Starfire. B5 was written by someone who knew nothing at all about Starfire. Both the Vorlons and the Shadows have 'Organic' technology. But in the B5 Universe, Organic tech is very much superior to all other (known) technologies. In order to "reproduce" the B5 setting, not only would you have to make the Shadows and Vorlons both "Organic" tech races, you'd have to boost the abilities of organic tech quite a bit in ways that would make them inherently superior to all the other races. Which would defeat the purpose of the game -- fair competition.
It might be an interesting "scenario" when a scenario editor is available.
Psychic technology is almost completely unrelated to "telepaths" as they exist in B5. The way that telepaths can screw up a Shadow ship is rather like the "Mental Flailer" though... makes the ship unable to attack.
But that should only work against Shadow ships in a B5 universe.
If they ever implement "Warp gates" though, we'll be able to change the game in at least one way to make it consistent with B5. Play without "natural" warp points and remove warp point manipulation techs. Just have warp gates.
