It allready has a bridge...and you can fly under it...re-live the SW Death Star flying_trough_trench experence...
I did use your basic model...but it's more detailed and smoother on some parts...still not done..that's why I'm posting this..
To tell the truth, I allso tought of putting cannons there, but they would be too much restricted... Don't worry, I destributed the firepower very good...
Against a Hecate they usualy end up destroying eachother...

Adn..what does a Vorlon Bridge look like?
EDIT: I allso made a higher poly version of the Paladin and gave it to the Freelancer modders. ...2142 polys (no turrets) so far...Once I texture it I'll post.
