Timestone Re: Jump Gates
""Jump Gates" are massive arrays organised in Groups of two to five generators, with each generator measuring between one and ten miles in length." However I can find no reference to proportions and I haven't come across any plans for Jump Gates. Babylon 5 Station is considered too fat and tall to fit through a Jump Gate, although a Minbari Cruiser would appear to be taller and I've got pictures of them coming though Jump Gates, I think?
I take it you need ratio's to model one. This link:

will give you profile views of all the B5 ships showing their size relative to one another and clicking on the image enlarges it to show scale relative to a 1 km bar. Other than this I can't yet help you and you may have to resort to estimating from images of ships in the process of making a "Jump".
This link will take you to the other races and is a good place for anyone wishing to model shipsets:
