And you could give those huge hive-ships an construction capability. So that they can construct an colony probe....(100kt ship with only possible component = colony component and 1 movement point to colonize) Let that ship be cheap so that it can be build in one turn.
So the hive ship only has to move from planet to planet and leave an colony probe on every planet and offcourse 1m population. Make some insectoid like shipset and race picture for them and I think it will be perfect (had those ideas for a while : insectoid trait)
Thats not a bad idea. However to do this I would have to make all the technology related to racial traits. That would mean a lot of copy's in the components file..... ohhhh the work in volved in that.

Note that the original poster did not intend to use a mod, so specific components will not work for him. Colonising everything is still valid though, but it is mandatory for any kind of Empire, Nomads/Pirates and barmy isolationists excepted.
