That won't work. I modified the GC2Types.xml file entry for one of the Huge ship types to this:
< Hull Name="HugeHull0" >
< DisplayName > Huge < / DisplayName >
< Description > Huge Hulls are for those mega ships. A Huge Hulled ship is over 3,000 meters long. They require 6 logistics points to coordinate so few fleets will have more than one of these. This would be the flag ship of your empire. < /Description >
< Cost >160< / Cost >
< Size >1000< / Size >
< SensorRange > 4 < / SensorRange >
< HP>200< / HP >
< Model >Huge_0 < / Model >
< Thumbnail > Huge_0 < / Thumbnail >
< Speed > 1 < / Speed >
< Category > Huge < / Category >
< Logistics > 8 < / Logistics >
< Tech_Requirement > Massive Scale Building < / Tech_Requirement >
Note: I've put spaces between some of the xml encodings so they still appear.
Sure, when building a huge ship, I had a size of 2000 to work with, but the size of all of the ship components increased exponentially. For example, Hyper Drive Mk. 3 suddenly had a size of 105! In the end, I still didn't have enough room on my ship to create an attack value of over 200 and still have considerable defenses, movement speed, and life support.
