I like that. It wouldn't even need to be a full station (size wise I mean) but more like a mobile command center. Maybe just call it like, Mobile Command Center Omega or something.
I was actually thinking something like this. Just move the transwarp gate to an asteroid field and plop down a prefab base on one of the asteroids where you could beam down and do your stuff. It's probably be small, so you might be able to get away with reusing the starbase/generic research station interior assets.
Considering that the KDF and Federation are still at war and have just agreed to not shoot each other in Gamma Orionis, I don't think that they would build a joint station. But someone else might build or transport them one, perhaps, like a crafty Ferengi?
Or they find one, mysteriously appearing out of nowhere?
You know, we never knew what happend to Deep Space 1, 2, 3, 4, 5, 6, 7 and 8? [/Babylon5Reference].
It would certainly come in handy to have the ability to change ships in Gamma Orionis.
