I was hoping to try to cut and paste different parts of the other caps for a quick-fix until I can model better (as I can't model at all right now). 
Another quick question regarding capital ships abilities - would it be possible to have a capital ship do:
A). Create a structure (Phase Stabilizer Node, Turret/Cannon, Broadcast Center?)
B.) Increase Diplomacy values (Reputation increases with 'blank' Faction if it is in the gravity well
My Ideas for the cap. ships was to have Vasari have a quick, large ship that could place a phase Stab. structure anywhere, at a large cost and with a large cool down period. The advent would have a culture increase, and the TEC would have a heavy weapon of some sort (Like the Beam from the Radiance Battleship for Advent - slightly different though).
These ships would have to be expensive, just for the sake that having even one of these ships should be in the late game or a combined effort to build.
