The Culture Mod

[Sabaoth]

I've been folling around some with my own race The Culture looseley based on the books by Iain Banks. Now i want to take my race one step further. In Banks books, The Culture travel in Huge General Construction Vehichels, home to millions of people, in addition to ringworld like orbitals. What i would like to do is a Mod where my race cant colonize planets. Instead of starting with planets they start with a number of GSV's, identical to SEIV planest in most aspects, but they can move around and they dont generate rescources. My race would later in the game, after some sturdy research work, be able to build orbitals and free floating habitats without the ability to move around.

Is it possible to create a mod for such vehichels?

I guess the main problem is to incorportate population on the ship, and make the production of the ship increase in proportion to the population.

Do you think this is a good idea, or am I just ranting?
