Except those two titles were highly ridiculed among the majority of civers. They are already bringing back bad ideas from past releases, no need to bring back bad sci-fi ones.
Of course, bad ideas should not ever be (re)implemented in the first place. My suggestion, in general, was simply suggest of either having future era expanded or new expansion set to Alpha Centauri (the game) theme. Albeit similar to the Colonization release for Civ4 some years ago. While also offering new Civs, units and such material to the core game.
