The other option is simply to add more population modifiers in setting.txt, since your big planets will eventually have more popualtion... if you base production/construction more on population instead of planet size, you can get the results your after. Currently I've modded it so all habitable planets have 25 facilities, this way the facilities just represent how you populations efforts are divided, but I have added numerous new lines of population modifiers... a huge world CAN but out ships twice as fast as large worlds... because huge worlds can have twice the population, and all my modifiers are linear in their bounus (although I gave a slight "increase for tiny and domed worlds, since the population would more likely be specialist than normal citizens)
