I have taken the artificial planets feature from THHGTTG mod and released it separately. This mod replaces econ bases with a new type of starbase, artificial planets! Unfortunately they function like starbases, not planets, but that can't be helped. Also, starbases and artificial planets now have to be researched.
TA compatibility has just been added, but in that version artificial planets appear much later, at the same time as Terror Stars.
This mod is for both DL, DA and TA and is currently pending in the library.
Changelog:
Version 0.5 fixes a major bug that was reported.
Version 0.6 adds DA compatibility and more interesting module names.
Version 0.7 fixes more bugs and adds a new planet model.
Version 0.8 adds TA compatibility.
And here's a screenshot:

If you wish to use the artificial planets in your mod, feel free, but please credit my work
